Filed .lune 25, 1965, Ser. No. 467,073 9 Claims. (Cl. 29-235) This invention relates to a machine for inserting tapes of pile weather stripping into the grooves of storm window extrusions. More particularly, it relates to a method and apparatus for incorporating ilexible tapes within long lengths of metal extrusions that will ultimately be cut and fabricated into storm door and window components requiring a weather seal with a cooperating movable member.

As is well known, storm windows and doors are fabricated from 16 or 18-fo0t lengths of extruded aluminum members which are cut to size and subsequently mitered together as a frame about a suitably sized window. Usually, tapes of wool pile material are inserted within complementary slots or grooves in the extrusions, the pile being adapted to abut against a cooperating member so as to act as a seal in keeping out drafts. In the past, the wool pile tapes were threaded into the slots of the 16 or 18- foot extrusions by hand. This would require a workman starting at one end of the extremely long extrusion, threading one end of the tape from a spool into the groove, and -then hand pulling the tape along the entire length of the extrusion. Such a manual operation necessarily resulted in a time-consuming and costly procedure. While machines for automatically inserting these tapes have been devveloped, it was difficult for the prior art machines to accommodate for changes in extrusion size, shape, and conformation as Well as for variations in gauge of the tape being dispensed. All in all, what prior machines had been made were expensive in operation and costly to maintain.

lt is therefore an object of this invention to provide a machine for automatically inserting ilexible weather stripping tapes into grooves of storm window extrusions.

Another object of this invention is to provide a machine for easily inserting such tapes and at the same time accommodating rapidly and efficiently for any variations in tape gauge or in extrusion size, shape and conformation.

Still another object of this invention is to provide an apparatus and method for etliciently and economically incorporating exible tapes of wool pile into the slots of storm window extrusions.

Yet another object of this invention is to provide a method for incorporating tapes of flexible material into slots of extrusions of any length.

Other objects of this invention are to provide an improved device of the character described which is easily and economically produced, that is sturdy in construction, and highly efficient and effective in operation.

With the above and related objects in view, this invention consists of the details of construction and combination of parts as will be more fully understood from the following detailed description when read in conjunction with the accompanying `drawing in which:

FIGURE 1 is atop plan view of a machine for inserting pile weather stripping into grooves of storm window extrusions.

-FIGURE 2 is an elevational view thereof taken generally along lines 2 2 of FIGURE 1.

FIGURE 3 is an enlarged fragmentary perspective view of the loading end of the machine.

FIGURE 4 is a fragmentary top plan view of the releasing or terminal end of the machine.

FIGURE 5 is a perspective view showing the manner in which the weather stripping is started into the extrusion groove.

FIGURE 6 is a sectional view taken along lines 6-6 of FIGURE 5.

Referring now in greater detail to the drawings in which similar reference characters refer to similar parts, the tape inserting machine of the instant invention comprises a frame, generally designated as A, a carrier member B longitudinally movable in said frame, and jaw means C secured to the carrier member and adapted to grasp tape D dispensed from a reel at one end of the machine and thread the same through an elongated extrusion E to the other end.

The frame A of the machine comprises a horizontal table member 10 supported by suitable legs 12 which can be made of angle iron, for example. Mounted at opposite ends of the frame A are bearings 14 and 16 for journalling the shafts of respective pulleys 18 and 20 about which a continuous carrier belt 22 is trained. The table top is approximately 18 feet long so as to accommodate the nominal standard l-foot lengths of extrusion stock E. An adjustable stop member 24 is bolted to the table top 10l at the discharge end of the machine and is adapted to orient and rapidly position each extrusion E with respect to the jaw means C in preparation for threading of the tape D therethrough.

The carrier member B which includes the belt 22 entrained about the pulleys 18 and 20, is driven by a conventional motor-gear reducer unit 26 so that the belt 22 will travel at a longitudinal speed of approximately 21/2 feet per second. A limit switch 28 is mounted at the loading end of the machine and has series contacts for connecting the motor 26 to a suitable source of electric power. The switch 28 may be a rotary, oil-tight limit switch, such as is described in Allen-Bradley Bulletin No. 802T and having a pivot arm 30. Moving rotary arm 30 by hand to the downwardly depending position shown by the dotted lines in FlGURE 3, will couple the motor 26 to the source of electrical power and cause said motor to run the carrier member B. The carrier member B will continue to run in a clockwise direction, as shown in FIGURE 3, until one of the jaw members C engages the switch arm 30, and cause it to turn upwardly through so as to open the internal switch contacts and stop the motor. At the other end of the machine and vertically opstanding from the table top 10 is a stationary vertical rod or post 32 which also is in the path of and engages the jaw means C as each passes thereby to release the tape D automatically at the end of each extrusion threading operation. See FIGURE 4.

The jaw means C and C1 comprise a pair of holding members which are secured to the belt 22 and are peripherally spaced from each other by Jaw C is adapted to grasp the end of the tape D after the latter has been partially threaded or engaged within the longitudinally extended slot or groove provided therefor in the extrusion E. After the jaw C has pulled the tape D through an extrusion E as a result of rotation of the carrier B and has automatically released the tape at the end of its stroke, the jaw C1, 180 in advance. will have engaged the arm 30 of switch 28 to cut off the power to the .motor 26. The jaw C1 will then coast around to the loading position previously occupied by the jaw C.

The jaws C and C1 are identical in every respect, each comprising a stationary portion 34 having a bracket or flange 36 secured to the belt 22 by bolts 38. A movable jaw 4l) is hingedly secured to the stationary jaw 34 and pivotally supported about trunnion 42. The lower porltion of the movable jaw 40 has a pad or cushion 41 which is adapted to abut the fixed jaw 34. A stud 44 is threaded into the fixed jaw 34 and freely extends through an opening 45 in the movable jaw 40 and its pad 41. Coil spring 46 is concentrically interposed about stud 44 'in compression between the stud head and the back of the movable jaw 40 so as to normally bias the latter into abutment with the xed jaw 34. Projection 39 at the inboard end of the movable jaw extends above the belt 22 and is adapted to open the movable jaw 4t) against the bias of the spring 46 either by hand during loading of the tape D or by abutment with the post 32 during its pass so as to automatically release the tape. The projecting arm 39 also serves to actuate the arm 30 so as to open the contacts of switch 28.

The tape D comprises long thin strips of backing 5t), approximately 1/32 inch thick by 1A inch wide, from which a somewhat narrow band of pile 52 extends outwardly. The strip 50 is inserted within a longitudinally extending slot or channel 54 in the extrusion E so that the pile portion 54 projects above the surface whereby the weather stripping C can perform its assigned task. The extrusions E are 16 or 18 feet long, and after the tapes D are inserted, they are cut and mitered to the appropriate size to frame the window itself.

The tape D is dispensed as a continuous roll from a reel 48 at the loading end of the machine. See `FIGURE 2. One end of the tape D is slightly twisted and sidled as shown in FIGURE 5 into the slot 54 at the proximal end of the extrusion E placed on the table top 1t). The jaw C overlying the loading end is manually opened by pressing against projection 39. The end of the tape D is grasped when the bias of the spring 46 closes the movable jaw member 40. The arm 30 is now swung downwardly by hand to close the switch 28 and actuate the motor power circuit. See FIGURE 3. The carrier lB will turn in a clockwise rotation, as shown in FIGURE l, and the jaw C will travel longitudinally with the belt 22. When the jaw C passes the post 32, projection 39 is engaged thereby to release the tape D after it has been entirely threaded through the extrusion slot S4. Meanwhile, `the jaw C1 will have moved around pulley 18 where its projection 39 will kick against the limit switch arm 30 to open the motor 26 contacts. The carrier B will coast around slightly until the jaw C1 is in loading position. The tape D is cut or broken at the proximal end overlying the loading portion of the table so that the tape threaded extrusion E now completed can be removed and a new extrusion loaded.
