VMy invention relates to devices for severing relatively wide webs of fabric or other material.
Where webs aremanufactured or treated as a continuous operation and the product or treated material'is formed -into rolls it is essential that the' severing of the web shall be accomplished in the space. of a fewseconds in order not to interruptthe continuous opermations of the forming or treating devices. It
is among the objects of my invention to p rovide'a'device, which shall be sufficiently quick in-operation to permit continued operation back of the cutter, shall be simple in struc- 'ture, economical to construct and operate,
' and substantially automatic in operation.
Other and further objects will be apparent from the following 'specification and claims. i In' the accompanying drawings which il-d lustrate one embodiment of my invention Figure lis a front elevation, Figure 2 is a plan view, Figure 3 is a section on'line 3=3 of Figure 2, y
Figure 4 is a sectional view similar to Figure 3 but showing the parts in position for the .severing operation, and Figure 5 is a view of a` modified form of 3o invention.
Referring tothe drawings `1 designates a 'base' member provided at its ends with uprights 2 and 3 rigidly supporting at their upper ends a transverse clamping and shearing bar 4. A-'second clamping bar 5 is guided on uprights 2 and 3, and adapted to be moved into clamping engagement with bar 4 by a compressed air cylinder 6 to the piston 7, of which bar 5 is secured. Cylinder 6 is mounted on base 1 and is supplied with air from an air line 8 conveniently controlled by a foot operated valve as at 9. The cutting instrumentalities comprise a series of pointed, vertically positioned knives 10 removably and adjustably secured in a transverse support 11, as by set screws 12. ISupport 11 is mounted for reciprocation in guides 13 secured to the under side of bar 5 .by bolts 14. The knife support 11 is adapted to be automatically reciprocated upon the movement MASSACHUSETTS, A CORPORATION 0F MASSACHU- WEi's-cuTTING DEVICE 192s; serial No. 105,327.
of the bar 5 into clamping position by means of an air cylinder 17 secured to bar 5 by bracket 18. The piston of cylinder 16 is operatively connected to the end of support 11 as indicated at 19. Air is admitted or exhausted alternately from opposite sides of the piston head through a conventional threeway valve 2O operated by plunger 22through a suitable pawl and ratchet not shown. As bar 5v rises into clamping position plunger 22 strikes stop 24 securedv to stationary bar 4 -into clamping position and simultaneously with the clamping of the fabric cylinder 17 operates to move support 11, and the knife assembly carried thereby, transversely to sever the web. As will be evident from'an inspection of Figure 1 the support 11 need travel only a distance equal to the space between adjacent knives in order to completely sever the web. If desired electrical or other means operated by support 11'or its associated parts,
may be provided to lower bar 5 upon completion of the cutting stroke. One manner of accomplishing this result is illustrated in Fig. 5 in which the foot pedal 9 lwhich admits fluid pressure tothe cylinder 6 has .been modified, as shown at 30, one arm being connected to the armature 31 of solenoid 33.
This solenoid is adapted to be energized from any suitable sources of current,the current passing through lead 34 through a spring Y switch 35, lead 36 to the solenoid back through lead 37 and through either switch 38 or switch 39, if either be closed, to lead 40. Secured to knife support 11 is a switch actuating finger 41. Switches 38 and 39 are of the conventional snap button type and with the parts inthe position shown in Fig. 5 switch 39 is open and switch 38 is closed. Assum 2 1,748.2@ i f -A ing foot pedal 30 to be now depressed to nthe second bar into clamping engagement admit fluid pressure to. cylinder 6, and withdrawing armature 31 from solenoid 33, knife support 11 will rise, as previously described, to pierce the fabric 16 as the support rises. Finger 41 will engage the button of switch 38 to snap it off so that when inger 41 engages and closes switch 35 both switches 38 and 39 are open. Stop 24 engaging valve plunger 22 vcauses the knife carrier' 11. to move to the right in Fig. to complete the cutting of the web, and finger -41 slides along switch 35,
,- which is thus held closed. As the knife support 11 completes the transverse severing movement linger 41 engages the button of switch 39 snapping that switch on, thus closing the circuit of the solenoid through that switch. Energizing of the solenoid draws armature 31 to the right thus relieving the 23 pressure in cylinder 6 and vpermitting bar 5 of the knife support to drop. This releases spring switch -35 opening the circuit and deenergizing solenoid 33; Finger 41 is lleft beneath switch 39 which is closed, switch 38 g5 being open so that upon the next upward movement of bar 5 and support 11 switch 39 will be switched off and upon transverse movement of bar 11, this time to the left, switch 38 `will be closed to energize solenoid :su 33 and return bar 5 to inoperative position.
The severing operation requires but a few seconds to complete and a single festoon roll placed back of the cutter will suffice to take .care of the material accumulated during the 35 cutting operation. *A
W'hile I have shown the knives as mounted p on the movable clamping bar it will be understood that they may be mounted onthe stationary bar if desired Without departing from .3" the spirit of my invention.
I claim: n u A y 1. A device of the character described com-y prising relatively movable clamping bars adapted to clamp a web therebetween, a plurality of spaced knives mounted for transverse. reciprocation on one of the clamping bars and adapted to pierce the web as the latwith the first named bar, a support mounted for reciprocation along the movable bar, a
plurality of vertically positioned knives mounted on said support and movable therewith, and means to automatically reciprocate said support transversely as the second named clamping bar reaches clamping position.
4. A- device of the character described comprising means to clamp a web, a pluralityy of spaced, vertically positioned knives associated with the clamping means and operable therewith to pierce the web asthe latter is engaged by the clamping means and means to move the knives transversely, while the web is lield'by the clamping means, to com- 'pletelyv sever the web.
In testimony whereof I have signed my name to the above specification.
