- the main shaft 2 is provided with a collar 11 which turns therewith, and this collar 11 is provided with a pawl 12 pivoted thereto.
- the said pawl 12 is urged to its outer position by means of a compression spring 14.
- theloose pulley 4 is hen the pawl 12 engages said internal teeth 15, the pulley 4 and the shaft 2 turn in unison. Nhen the pulley 4 has turned approximately a full revolution, the pin 10 engages the pawl 12 and pushes it inwardly so that it releases the internal teeth 15. This permitsthe pulley 4 to turn freely while the shaft 2 remains stationary.
- the pawl 12 is released to again engage the teeth 15.
- the shaft 2 is caused to turn for approximately a full revolution and it is then released.
- Fig. 1 wide strip of tape T and a narrow strip of tape Ta are fed into the machine.
- the wide piece of tape is cut into pieces to form the button or snap fastener reinforcement for'thc slit of the glove blank 100.
- Fig. 17 shows one of these pieces which is identified by the reference'numeral 101.
- the pieces which are cut from the nar- 5 row tape Ta form slit reinforcements 102.
- these slit reinforcements 102 may be cut so as to have recesses which are aligned with the slit 103 of the blank.
- the use of such a recess in the reinforcement 102 is well known. Since the mechanisms for feeding l the tape T and the tape Ta are identical, only oneof them is illustrated in detail in Fig. 11.
- the tape T passes through a feed box 22.
- the details of the said feed box 22, and of the appurtenant parts, are shown in Figs. 1216 inclusive.
- the feed box 22 is provided with a support 23 for the tape, said support 23 being connected in any suitable manner to the feed box 22, so that there is no relative movement between the support 23 and the feed box 22.
- this stationary member 23 is provided with a stationary spring tongue 23a. Hence, the teeth 24 of the feed dog 24a can project above the said tongue 23a on both sides thereof.
- the extension 27 of the feed dog 24a is connected to a link 29 which is connected to a lever 30 pivotally connected to the frame of the machine at 31.
- Said lever 30 has a roller 32 which cooperates with a cam 33 mounted upon the second cam shaft 34.
- the turning of the cam 33 causes the lever 30 to rock back and forth so that the feed dog 24a is reciprocated, and is also moved up and down so that the teeth 24 engage the tape on the forward feeding movement, and release the tape upon the backward stroke of the feed dog 24a.
- the bottom of the feed box 22 is slotted so as to permit the extension 27 of the feed dog 24a to move up and down and to also slide back and forth.
- the extension 27 is close to the adjacent end of the slide 26, so that the feed dog 24a is normally held in such position that its teeth 24 are close to, but do not engage the tape T.
- the lever 30 is turned in the clockwise direction, this causes the feed dog 24a to be tilted upwardly and to be also moved forward so is to be understood that any suitable spring can be used for keeping the roller 32 of the lever in constant engagement with the cam 33, such spring not being shown in the drawings as in itself, itis oldand well known.
- a similar feed dog construction is utilized for feeding'the narrow tape Ta so that both tapes T and Ta are fed simultaneously and equally.
- the respective feed boxes 22 for the tapes are parallel to each other and said feed boxes 22 maybe adjustable so that the distance between them can be varied. This makes it possible to vary the spacing between the members 101 and 102 ployed is shown in Fig. 11, it being understood that the construction, operation and movement of the other cutting device is similar since both cutting devices are operated by the same means.
- the knife 36 is adjustably connected to the holder 37 by means of set screws 38 which pass through slots in the knife 36.
- the holder 37 is provided with an extension 39.
- the extension 39 is mounted'upon a rock shaft 37a and said eX- tension 39 is pivotally connected at 394 to a link 39?) which is slidably mounted on the shaft 34.
- Said link 39?) is provided with a roller 390 which cooperates with cam 39d,
- the pneumatic head P is connected to two lines of hose 84 and 84.
- One of these hose lines is connected to a vacuum pump or the like, for producing suction and the other hose line is connected to a suitable pump or the like for supplying air under pressure.
- a Vacuum is created in the suction head P, it serves to firmly hold the Severed pieces of tape to its perforated I under face which is shown in Fig. 9.
- compressed air is supplied to the pneumatic head P this causes the pieces'of tape to be applied with suitable pressure to the slit 103 of the blank 100.
- the pressure is utilized after the adhesive has been supplied to the under-faces of the severed pieces of tape.
- the shaft 34 is provided with a sprocket 40 which is driven by means of chain 41 and sprocket 42 located on the transverse shaft .18.
- the pneumatic head P is suitably connected to a bar 43 which is pivotally connected at 44' to an upright 45 which is rigidly connected to a slidable' bar 4?.
- Said slidable bar 46 moves in bearings 4
- the pneumatic head P is clamped into position by means of clamping bars 52 which are connected to the pivoted bar 43 by means of screws 53.
- one side of the pivoted bar 43 is connected to a U-shaped member 48 which is provided with a pin 49 connected to slide 50. Said slide 50 moves in the guide bar 51.
- an arm 55 whose length can be adjusted by nut member 550, is pivotally connected to the bar 46 at 54.
- the arm is pivotally connected at 56 to the lever 57 which is pivotally connected at 58 to the frame of the machine.
- the lever 58 is pivotally connected at 59 to a slotted arm 60 which slides upon the transverse main cam shaft 18.
- Said ar1n 60 is provided with a roller 61 which fits in the cam groove 62 of the cam 63, whichis mounted on the shaft 18.
- the guide bar 51 is pivotally connected at 64 to theframe of the machine and it may be provided with a counterweight 65 to balance the weight of the pneumatic head P.
- the pivoted guide bar 51 is guided in its up and down movement between two uprights 68 forming part of the frame of the machine.
- a link. 66 is pivotally connected at 67 to the pivoted guide bar 51 and this link 66 is pivotally connected at 70 to a lever 71 which is pivotally connected at 72 to the frame of the machine.
- Said lever 71 is provided with a cam roller 73 which operates in the cam groove of a cam 74,which is mounted upon I the shaft 18. 1
- the pneumatic head P is caused to slide back and forth and to also move up and down, the movement thereof being indicated in dotted lines in Fig, 6.
- the up and down component of the movement thus illustrated in Fig. 6 is to cause the adhesive to be properly applied to the under face'of the pieces of tape severed from T and Ta.
- the adhesive which is applied to the severed pieces of tape is preferably a quick drying rubber cement. This cement is applied to the severed pieces of tape by means of a well known mechanism which requires only The thick rubber cement is held in a casing 75 provided with a knurled applying roller 76.
- the casing 75 is provided with a shaft 77 having a bevel gear 78 driven by bevel gear 79 on shaft 80 pulley 4.
- the device operates to cause a thin. film of the adhesive to continuously cover the roller 7 6 which is mounted on a shaft having a. pulley connected by a belt 76a to a similar pulley on the shaft 77.
- the vertical or up and down movement of the pneumatic head P is designed to prevent the adhesive from being applied to the front edge or to the rear edge of each severed piece of tape. That is, the film of adhesive which is applied to the under face of each piece of tape, is slightly spaced from the front edge and from the rear edge thereof. It would not be departing from my invention if the film of adhesive were only spaced from one of the edges of the piece of tape, but I prefer to have it spaced both from the front edge and from the rear edge. Since rubber cement is thick a globule thereof tends to form upon the severed piece of tape when it is pulled away from the applying roller. This excess of adhesive would tend to spread out beyond the edges of the piece of tape, when it was finally applied to the blank.
- the glove blanks to be operated upon are placed upon the movable worktable 82 which is slidably mounted in guides 83 connected to the frame of the machine.
- This table 82 is reciprocated towards and away from the operator.
- said table 82 has a link 84 pivotally connected to the underside thereof.
- the link 84 is pivotally connected at 85 to a lever 86 which is pivotally connected at 87 to the frame of the machine.
- Said lever 86 has a roller 88 which operates in the cam groove of a cam 89 mounted upon the main sh aft 2.
- the guide plate 83c which has the uide flanges 83, has the rear end thereof cut out so that the severed pieces of tape can contact with the roller 76.
- the hose line 84; of the pneumatic. head P may be designated for convenience, as the suction line, and the hose line 8st may be design ated as the pressure line.
- the valve for controlling the admission and cut-ell of air under pres are is of any suitable type. and it is slidably mounted in the casing 86?), and it is operated by means of a solenoid which is not shown, as solenoid operated valves are in themselves old and well known and form no part of my invention.
- a solenoid which is not shown, as solenoid operated valves are in themselves old and well known and form no part of my invention.
- the electric control for the solenoids in the casings 86a and 867) is diagrammatically shown in Figs. 18 and 19.
- the switch control for the solenoid in casing 866 comprises a pair of levers 92 and 92a provided with rollers attheir upper ends.
- the switch. disk 90 is preferably made of wood or other insulating material and it is provided with a short metal strip 95 and a long metal strip 93 which are laterally spaced from each other.
- the switch control for the solenoid in casing 86a comprises a pair of levers 91 and 91a having rollers adapted to contact with the metal strip 93.
- WVhile two disks 9() are shown in Fig. 18, this is merely for the sake of clearness because the switch roller comprises a single disk 90 made of insulating material and having a short metal strip 95 at one side adapted to cooperate with the levers 92 and 92a, and having along metal strip 93 on the other side adapted to cooperate with the .evcrs 91 and 91a. It is clear that when the levr s 92 and 9260 contact with the short metal strip 95, that air under pressure is supplied to the pneumatic head. Likewise, when the levers 91 and 91a contact with the long meta strip 93, suction is applied to the pneumatic head P.
- the operator suitably adjusts the boxes 22 so that they are properly spaced from each other corresponding to the desired spacing for the members 101 and 10:2.
- the movable worktable .82 is in its outer position;
- the operator then places a blank in suitable position upon the movable worktable 82 and then presses upon the treadle 6.
- This operates the clutch so that the pulley 4 connected to the main shaft 2.
- the feed dogs 24a then operate to forwardly feed the tapes T and To until their free ends rest upon the cutting table 35.
- the pneumatic head P then. descends and suction may be created at this point in the pneumatic head P so as to firmly hold the freeends of the tapes T and id in position, although the pressure with which the pneumatic head P is forced down, would be sufficient for this purpose.
- the knives 36 are then operated to sever the ends of the tapes T and Ta. Suction must be applied at this point to the pneumatic head P.
- the pneumatic head P is then raised above the worktable 8.2 and itis moved laterally, its path of movement having a vertical component sothat each of the pieces of tape is supplied with a thin film of rubber cement at its underside, Without any excess adhesive being taken up.
- the pneumatic head P is finally moved to the lefthand position indicated in dotted lines in Fig; 6, the worktable 82 being moved inwardly so as to present the blank in proper position.
- the pneumatic head P is then caused to descend and when the pieces of tape are pressed against the blank, 7
- V bers 101 and 102 are properly pasted into position.
- the clutch is automatically tripped after the slidable worktable 82 has moved to its outer position. At this time, the pneumatic head P is at the full-line position illustrated in Fig. 6 so that the machine is ready for. another operation.
- the cutting knives may have any suitableshape so as to give any desired shape to the members 101 and 102, it being understood that the rectangular shape illustrated in Fig. 17 is merely illustrative.
- tension springs S are utilized for holding the respective levers 91 and 92 so that they will contact with the respective metal strips on the switch roller 90. 7
- the severed pieces oftape should not completely obstruct the perforated bottom face of the pneumatic head P. Hence when suction is applied, air can pass around the severed pieces of tape. Likewise, when air under pressure is applied to the pneumatic head P, it can pass out of the said pneumatic head P. However, it would not be departing from my invention if the perforations in the pneumatic head P were so arranged so that they were substantially closed by the severed pieces of tape.
- the pneumatic head P could be connected to a single hose line with suitable valves and control means for connecting this single hose line to vacuum producing means, and to a source of air under pressure.
- a pneumatic head means adapted to create a vacuum-in said head, means adapted to supply air under pressure to said head, first control means adapted to control said vacuum producing means, second control means adapted to con trol said means for supplying air under pressure, operating mechanism adapted to apply the said pneumatic head to the first piece of material, said first control means being then operative to enable a vacuum to be produced in said head so that the first piece ofmaterial clings to said head, adhesive-supplying means, said operating mechanism being adapted to cause the piece of material clinging to said pneumatic head to contact with said adhesive-supplying means so as to pro Jerusalem a film of adhesiveupon the exposed face of said first piece of material, said operating means being then adapted to cause said first piece of material to contact with the second piece of material, said first controlmeans being adapted to cause said vacuum producing means to thenbecome inoperative, said second control means being adapted to then cause air under pressure to

The said pawl 12 is urged to its outer position by means of a compression spring 14.-
As shown in Fig. 7, theloose pulley 4 is hen the pawl 12 engages said internal teeth 15, the pulley 4 and the shaft 2 turn in unison. Nhen the pulley 4 has turned approximately a full revolution, the pin 10 engages the pawl 12 and pushes it inwardly so that it releases the internal teeth 15. This permitsthe pulley 4 to turn freely while the shaft 2 remains stationary. By pressing the treadle 6 so as to move the clutch pin 10 in a direction perpendicular to the plane of the paper in Fig. 7,
the pawl 12 is released to again engage the teeth 15. Hence, when the operator presses upon the treadle 6 and then releases the same, the shaft 2 is caused to turn for approximately a full revolution and it is then released.
Asshown in Fig. 2, the main shaft 2 is provided with a bevel gear 16 which meshes with a bevel gear 17 mounted on the transverse shaft 18. As shown more partlcularly in Fig. 3, the shaft 18 is the main cam shaft of the machine. I
' As shown in Fig. 1, wide strip of tape T and a narrow strip of tape Ta are fed into the machine. The wide piece of tape is cut into pieces to form the button or snap fastener reinforcement for'thc slit of the glove blank 100. Fig. 17 shows one of these pieces which is identified by the reference'numeral 101. The pieces which are cut from the nar- 5 row tape Ta form slit reinforcements 102. If
desired, these slit reinforcements 102 may be cut so as to have recesses which are aligned with the slit 103 of the blank. The use of such a recess in the reinforcement 102 is well known. Since the mechanisms for feeding l the tape T and the tape Ta are identical, only oneof them is illustrated in detail in Fig. 11. This shows the strip of tape T wound into a roll R on a spool or the like, which is mounted upon a suitable shaft supported in bracket 21 which is either mounted adjacent to or is suitably connected to the frame of the machine. The tape T passes through a feed box 22. The details of the said feed box 22, and of the appurtenant parts, are shown in Figs. 1216 inclusive. The feed box 22 is provided with a support 23 for the tape, said support 23 being connected in any suitable manner to the feed box 22, so that there is no relative movement between the support 23 and the feed box 22. As shown in 13, this stationary member 23 is provided with a stationary spring tongue 23a. Hence, the teeth 24 of the feed dog 24a can project above the said tongue 23a on both sides thereof.
The feed dog 24/; is pivotally connected at 25 to a slide 26, which is slidably mounted in the feed box 22. The feed dog 24a is provided with an extension 27 which serves to manipulate the same. The slide 26 is guided to slide in suitable position within the feed box 22 by means of the blade spring 28 which is connected to a side wall of the box 22. The free end of the blade spring 28 extends through a recess in said side wall so that said free end presses against the slide 26.
As shown in Fig. 11, the extension 27 of the feed dog 24a is connected to a link 29 which is connected to a lever 30 pivotally connected to the frame of the machine at 31. Said lever 30 has a roller 32 which cooperates with a cam 33 mounted upon the second cam shaft 34. The turning of the cam 33 causes the lever 30 to rock back and forth so that the feed dog 24a is reciprocated, and is also moved up and down so that the teeth 24 engage the tape on the forward feeding movement, and release the tape upon the backward stroke of the feed dog 24a. The bottom of the feed box 22 is slotted so as to permit the extension 27 of the feed dog 24a to move up and down and to also slide back and forth.
As shown in Fig. 12', for example, the extension 27 is close to the adjacent end of the slide 26, so that the feed dog 24a is normally held in such position that its teeth 24 are close to, but do not engage the tape T. lVhen the lever 30 is turned in the clockwise direction, this causes the feed dog 24a to be tilted upwardly and to be also moved forward so is to be understood that any suitable spring can be used for keeping the roller 32 of the lever in constant engagement with the cam 33, such spring not being shown in the drawings as in itself, itis oldand well known.
A similar feed dog construction is utilized for feeding'the narrow tape Ta so that both tapes T and Ta are fed simultaneously and equally.
As shown in Fig. 1, the respective feed boxes 22 for the tapes are parallel to each other and said feed boxes 22 maybe adjustable so that the distance between them can be varied. This makes it possible to vary the spacing between the members 101 and 102 ployed is shown in Fig. 11, it being understood that the construction, operation and movement of the other cutting device is similar since both cutting devices are operated by the same means.
As shown in Fig. 11, the knife 36 is adjustably connected to the holder 37 by means of set screws 38 which pass through slots in the knife 36. The holder 37 is provided with an extension 39.
As shown in Fig. 5, the extension 39 is mounted'upon a rock shaft 37a and said eX- tension 39 is pivotally connected at 394 to a link 39?) which is slidably mounted on the shaft 34. Said link 39?) is provided with a roller 390 which cooperates with cam 39d,
which is mounted on said shaft 34. It is to be understood that both knives are mounted upon and are actuatedby the same rock shaft. The action of said knives is clearly shown in Fig. 5.
As shown in Fig.3, the pneumatic head P is connected to two lines of hose 84 and 84. One of these hose lines is connected to a vacuum pump or the like, for producing suction and the other hose line is connected to a suitable pump or the like for supplying air under pressure. 'When a Vacuum is created in the suction head P, it serves to firmly hold the Severed pieces of tape to its perforated I under face which is shown in Fig. 9. When compressed air is supplied to the pneumatic head P this causes the pieces'of tape to be applied with suitable pressure to the slit 103 of the blank 100. The pressure is utilized after the adhesive has been supplied to the under-faces of the severed pieces of tape. As shown in Fig. 3, the shaft 34 is provided with a sprocket 40 which is driven by means of chain 41 and sprocket 42 located on the transverse shaft .18.
general illustration in the drawings.
As shown in Fig. 5, the pneumatic head P is suitably connected to a bar 43 which is pivotally connected at 44' to an upright 45 which is rigidly connected to a slidable' bar 4?. Said slidable bar 46 moves in bearings 4 As shown in Figs. 2 and 10, the pneumatic head P is clamped into position by means of clamping bars 52 which are connected to the pivoted bar 43 by means of screws 53.
As shown in Fig. 10, one side of the pivoted bar 43 is connected to a U-shaped member 48 which is provided with a pin 49 connected to slide 50. Said slide 50 moves in the guide bar 51.
As shown in Fig. 4, an arm 55, whose length can be adjusted by nut member 550, is pivotally connected to the bar 46 at 54. As shown in Fig. 5, the arm is pivotally connected at 56 to the lever 57 which is pivotally connected at 58 to the frame of the machine. The lever 58 is pivotally connected at 59 to a slotted arm 60 which slides upon the transverse main cam shaft 18. Said ar1n 60 is provided with a roller 61 which fits in the cam groove 62 of the cam 63, whichis mounted on the shaft 18. The guide bar 51 is pivotally connected at 64 to theframe of the machine and it may be provided with a counterweight 65 to balance the weight of the pneumatic head P. Likewise, the pivoted guide bar 51 is guided in its up and down movement between two uprights 68 forming part of the frame of the machine.
A link. 66 is pivotally connected at 67 to the pivoted guide bar 51 and this link 66 is pivotally connected at 70 to a lever 71 which is pivotally connected at 72 to the frame of the machine. Said lever 71 is provided with a cam roller 73 which operates in the cam groove of a cam 74,which is mounted upon I the shaft 18. 1
Hence, the pneumatic head P is caused to slide back and forth and to also move up and down, the movement thereof being indicated in dotted lines in Fig, 6.
The up and down component of the movement thus illustrated in Fig. 6 is to cause the adhesive to be properly applied to the under face'of the pieces of tape severed from T and Ta. The adhesive which is applied to the severed pieces of tape is preferably a quick drying rubber cement. This cement is applied to the severed pieces of tape by means of a well known mechanism which requires only The thick rubber cement is held in a casing 75 provided with a knurled applying roller 76.
As shown in Fig. 4, for example, the casing 75 is provided with a shaft 77 having a bevel gear 78 driven by bevel gear 79 on shaft 80 pulley 4.
The device operates to cause a thin. film of the adhesive to continuously cover the roller 7 6 which is mounted on a shaft having a. pulley connected by a belt 76a to a similar pulley on the shaft 77.
The vertical or up and down movement of the pneumatic head P is designed to prevent the adhesive from being applied to the front edge or to the rear edge of each severed piece of tape. That is, the film of adhesive which is applied to the under face of each piece of tape, is slightly spaced from the front edge and from the rear edge thereof. It would not be departing from my invention if the film of adhesive were only spaced from one of the edges of the piece of tape, but I prefer to have it spaced both from the front edge and from the rear edge. Since rubber cement is thick a globule thereof tends to form upon the severed piece of tape when it is pulled away from the applying roller. This excess of adhesive would tend to spread out beyond the edges of the piece of tape, when it was finally applied to the blank. As this would be highly objectionable, it is an important feature of my invention to confine the film of adhesiy e within the edges (or within a sullicient number of edges) of each severed piece of tape so that when the piece of tape is finally pasted into position, the film of adhesive does not extend beyond the edges thereof.
The glove blanks to be operated upon are placed upon the movable worktable 82 which is slidably mounted in guides 83 connected to the frame of the machine. This table 82 is reciprocated towards and away from the operator.
As shown in Fig. 3. said table 82 has a link 84 pivotally connected to the underside thereof. The link 84 is pivotally connected at 85 to a lever 86 which is pivotally connected at 87 to the frame of the machine. Said lever 86 has a roller 88 which operates in the cam groove of a cam 89 mounted upon the main sh aft 2.
As shown in Fig. l, the guide plate 83c which has the uide flanges 83, has the rear end thereof cut out so that the severed pieces of tape can contact with the roller 76.
The hose line 84; of the pneumatic. head P may be designated for convenience, as the suction line, and the hose line 8st may be design ated as the pressure line.
The valve for controlling the admission and cut-ell of air under pres are is of any suitable type. and it is slidably mounted in the casing 86?), and it is operated by means of a solenoid which is not shown, as solenoid operated valves are in themselves old and well known and form no part of my invention. When the pipes 8'57) and 887) communicate with each other, air under pressure is supplied to the hose 8%. controlling the suction of air through the head P is similar type and it is mounted in casing 860 Said valve provides or prevents communication between the pipes 870 The valve for and 880. It is understood that the hose lines 84 and 84 may be connected to the pipes 870 and 87?) and that the pipe 880 may be connected to a vacuum pump or the like, and that the pipe 88?) may beconnected to a pressure pump or the like. The electric control for the solenoids in the casings 86a and 867) is diagrammatically shown in Figs. 18 and 19. The switch control for the solenoid in casing 866 comprises a pair of levers 92 and 92a provided with rollers attheir upper ends. The switch. disk 90 is preferably made of wood or other insulating material and it is provided with a short metal strip 95 and a long metal strip 93 which are laterally spaced from each other. The switch control for the solenoid in casing 86a comprises a pair of levers 91 and 91a having rollers adapted to contact with the metal strip 93. WVhile two disks 9() are shown in Fig. 18, this is merely for the sake of clearness because the switch roller comprises a single disk 90 made of insulating material and having a short metal strip 95 at one side adapted to cooperate with the levers 92 and 92a, and having along metal strip 93 on the other side adapted to cooperate with the .evcrs 91 and 91a. It is clear that when the levr s 92 and 9260 contact with the short metal strip 95, that air under pressure is supplied to the pneumatic head. Likewise, when the levers 91 and 91a contact with the long meta strip 93, suction is applied to the pneumatic head P.
The complete operation of my method and my machine is as follows: i
The operator suitably adjusts the boxes 22 so that they are properly spaced from each other corresponding to the desired spacing for the members 101 and 10:2. At this point the movable worktable .82 is in its outer position; The operator then places a blank in suitable position upon the movable worktable 82 and then presses upon the treadle 6. This operates the clutch so that the pulley 4 connected to the main shaft 2. The feed dogs 24a then operate to forwardly feed the tapes T and To until their free ends rest upon the cutting table 35. The pneumatic head P then. descends and suction may be created at this point in the pneumatic head P so as to firmly hold the freeends of the tapes T and id in position, although the pressure with which the pneumatic head P is forced down, would be sufficient for this purpose.
The knives 36 are then operated to sever the ends of the tapes T and Ta. Suction must be applied at this point to the pneumatic head P. The pneumatic head P is then raised above the worktable 8.2 and itis moved laterally, its path of movement having a vertical component sothat each of the pieces of tape is supplied with a thin film of rubber cement at its underside, Without any excess adhesive being taken up. The pneumatic head P is finally moved to the lefthand position indicated in dotted lines in Fig; 6, the worktable 82 being moved inwardly so as to present the blank in proper position. The pneumatic head P is then caused to descend and when the pieces of tape are pressed against the blank, 7
V bers 101 and 102 are properly pasted into position.
The clutch is automatically tripped after the slidable worktable 82 has moved to its outer position. At this time, the pneumatic head P is at the full-line position illustrated in Fig. 6 so that the machine is ready for. another operation. The cutting knives may have any suitableshape so as to give any desired shape to the members 101 and 102, it being understood that the rectangular shape illustrated in Fig. 17 is merely illustrative.
As shown in Fig. 8, tension springs S are utilized for holding the respective levers 91 and 92 so that they will contact with the respective metal strips on the switch roller 90. 7
As shown in Fig. 9, I prefer that the severed pieces oftape should not completely obstruct the perforated bottom face of the pneumatic head P. Hence when suction is applied, air can pass around the severed pieces of tape. Likewise, when air under pressure is applied to the pneumatic head P, it can pass out of the said pneumatic head P. However, it would not be departing from my invention if the perforations in the pneumatic head P were so arranged so that they were substantially closed by the severed pieces of tape.
While I have shown a completely organized semi-automatic machine, I do not wish to be limited to the complete machine described, as many of the 'subcombinations thereof could be separately utilized whenever it is desired. to connect one piece of material to another by means of an adhesive.
For example, it can be readily seen that the pneumatic head P could be connected to a single hose line with suitable valves and control means for connecting this single hose line to vacuum producing means, and to a source of air under pressure.
Likewise, while I have shown the piece of tape being moved towards and across and away from the adhesive-applying means 76,
I am not to be limited to this particular movement as the essential feature of this portion of my invention is to produce a relative movement between the piece ofmaterial and the adhesive-applying means which shall prevent excess of adhesive from being suppliedto the piece of material. Likewise, it is well known to provide tape with a layer of dry adhesive and to render said adhesive operative by inoistening the same. It therefore would not be departing from myinvention if the adhesive-applying means were replaced by moistening means or the like across which a piece of tape having a layer of dry adhesive could be moved, in. order to moisten said adhesive and render the same operative.
Generally speaking, while Ihave shown a preferred embodiment of my invention, it is clear that numerous changes and omissi'ons could be made without departing from i the spirit of my invention.
