This invention relates to improvements in a i machine for manufacturing binding tapes.

or flat metal strand and a padding adhered thereto which is largely automatic and is of large capacity, requiring little attention on the part of the operator.

Second, to provide a machine of this character which produces a very uniform product.

Objects relating to details and economies of the invention will appear from the description lto follow. The invention is pointed out in the claims. A preferred embodiment of the invention is illustrated in the accompanying drawings, in

As stated, the embodiment of the invention illustrated is especially designed for making the binding tape, the subject matter of the Wall and Reinhard Patent 2,570,615. The machine is in some respects an embodiment of and ain improvement on the structure of the patent to Boersma and Robinson No. 2,560,923, issued July 17, 1951.

The binding tape which is designated generally by the numeral I in Fig. 4 comprises a metal ribbon or strand element 2, a padding element 3, and a padding backing strip i of paper interposed between the metal strand and the padding. The backing strip 4 is of a width substantially exceeding the width of the metal strand and is adhered to the inner side of the metal strand. The padding, which is desirably formed of multiply tissue folded upon itself, is adhered to the inner side of the supporting strip 4.

The machine of this application is designed to form the padding element 3 (see Fig. 8) from multiply strips of tissue 'I (see Fig. 7) and to apply the supporting strip or element i to the conformed padding strip to produce the composite strip designated generally by the numeral 8 in Fig. 9. The composite strip 8 is first formed as a continuous strip and is then cut into sections and adhesively secured to the metal ribbon or strand element 2 with the adjacent ends of the sections in spaced relation to each other and spaced relative to the scores 5 in the metal element indicated in Fig. 4 by dotted lines. These scores facilitate the breaking or severing of the continuous strip into tie length and provide tie sections 6 at each end of the padding. One use of this material is illustrated in the Wall and Reinhard Patent 2,57 0,614.

For convenience and economy in manufacture the operative parts are supported on frames designated generally by the numerals l0, II, I2, I3 and I4, these being arranged in alignment. The frame I0 is designed to support a plurality of reels or spools I5 for strips of padding material 'I and a spool or reel I6 for the strip of padding backing material 4. As illustrated, two strips of the padding material are employed in forming the padding element.

The strips l are guided by the guide rollers Il, conventionally shown in Fig. 1, to the forming member I8 which is provided with converging edge folders I9 which'fold the edges of the padding material upwardly and inwardly into edge the chain 33 and suitable sprockets.

`abutting relation as shown at Eil in Fig. 8. The

padding supporting strip 4 is guided by the roller 2l to the guide throat 22 disposed in advance of the glue or adhesive applying roller 24, this roller dipping into the adhesive receptacle 25. From the glue roller the strip 4 is guided by the guide throat into superimposed relation to the padding strip and its Vadhesive surface is superimposed upon the inturned edges of the padding strip as is shown in Fig. 9.

The padding material and the backing niaterial therefor is drawn from the spools or reels and through the forming dies and across the adhesive applying roller by means of the coacting pressure and feed belts designated generally by the numerals 1 and 28, these being supported so that their opposed reaches travel rearwardly and apply driving and sealing pressure to the composite strip. The belts are trained over the rollers 29 and 29 which are gea-red to each other and driven by the chain 34 from the transmission assembly designated generally by the numeral 3|. This transmission assembly is driven from a motor 32 through As the details of this mechanism are not part of this invention they are not illustrated herein. This first pair of feed and driving belts are the same in structure as the second pair of feed and driving belts which are illustrated in more detail v in Fig. 3 and will be described later.

VThe rst pair of feed and pressure belts are of such length as to allow the adhesive toset before the composite strip is discharged from the belts. As it is discharged from these belts it is formed into a take-up loop 34 and the loop is given a half twist, as indicated at 35, so that as discharged over the guide roller 95 the padding supporting element 4 is on the under side of the composite strip as shown in Fig. l0, it being shown in Fig. 9 in the position in which it is discharged from the first pair of feed and pressure belts. The speed of the machine is controlled by the hand wheel 31, the sprocket chain 31 and suitable sprockets to the driven shaft of the variable speed transmission assembly (see Fig. l) The loop is formed by the difference in speed of the pad forming machine, and the metallic strip applying machine.

From the roller 36 the composite strip is passed through the guide 38 to the feed rollers 39 and 49, the feed roller '39 being a driven roller and the feed roller 4t a pressure roller. At the rear of the feed rollers is a cutter comprising a cutter bar 4| and the reciprocating cuti ter blade or knife 42. At the rear of the knife is a guide 43 having an opening 44 in its under wall through which the glue or adhesive applying roller 45 projects to coact with the paddingV backing strip 4 of the composite strip 8 which is then in position with its padding supporting strip 4 downward or on thev under side. The guide 43 directs the composite strip with the adhesive thereon to the second pair of the feed and pressure belts 45, the adjacent cooperating reaches thereof traveling rearwardly. A series of belt supporting rollers 41 are provided for the opposed reaches of the belts so that the belts are firmly pressed against the work passing therebetween. The ribbon steel element 2 is` `directedby Vthe guide 48 against the lower belt as it passes around the front pulley 49, as shown in Fig. 3, so that the metal strand is directed upon and pressed against Vthe adhesive bearing surface of the strip 4. The rear ends of the belts 46 are supported and driven by the pulleys 50 which are geared together, the gears not being shown.

The lower pulley 58 is driven by the sprocket chain 5i coacting with a suitable sprocket on the jacksha'ft 52.' The metal element or strand 2 is drawn from a spool or reel 2 on the frame or pedestal I3. The upper feed belts of both units are adjustably supported by means of the screws 53 for regulating the pressure thereof and adjusting thesame to the thickness of the material used.

The scores, indicated at 5 in Fig. 4, are formed by means of the serrated or toothed scoring blade 54 mounted on the roller 55 in opposed relation to the supporting roller 56. The roller 55 is provided with a bearing member 51 adjustably supported in the frame 58 by means of the screws 59, only one of which is illustrated. The roller or scoring blade 54 is driven in timed relation to the lintermittent feed roller 39 so that the composite strip sections delivered from the intermittent feed roller and the cutter to the feed and pressure belts are delivered with their ends in spaced relation to the scores of the metal strand element providing the tie sections ll.

To drive these several parts in timed relation the jackshaft 52 is driven from the driven shaft of the variable speed transmission by the driving chaink 59 on the sprocket 6| on the jackshaft. The driving roller 39 and the glue roller 45 are driven from the jackshaft through the chain 92 and a sprocket indicated at 63 on the jackshaft. The shaft 64 of the feed roller 39 is intermittently driven'through the clutch designated generally by the numeral 65. The details of this clutch are not illustrated'but it is actuated through the rockshaft 66 having an arm 51 coacting with the clutch actuating member 68. The rockshaft is provided with an arm 59 with which the cam 10 on the shaft 1| coacts. The shaft 1| is driven through the clutch 'i2 and the sprocket chain 13 to the jackshafts 52. 'Ihe clutch actuating arm 14 is actuated through the tappet arm 15 which is positioned to be engaged by tappets 16 on the sprocket chain 1l. rIhis sprocket chain is ydesigned to be lengthened and shortened by taking out one or more links, it being adjustably supported by the adjustable sprockets 18 (see Fig. 1). The arm 14 is connected by the link 19 to the clutch actuating arm 8U for the scoring cutter 55. The details of these clutches are not illustrated as they form no part of the present invention.

The shaft 1l is provided with a cam 8i which coacts with the roller 82 on. the lower end of the connecting rod 83 which is supported by the Y rocker arm 84 at its lower end and is connected to the cutter actuating lever 85 pivoted at 83 and pivotally connected at 81 to the cutter blade 42. A spring 88 is provided for retracting the cutter blade.

The feed roller 39 is provided with an overrunning clutch, designated generally by the numeral 89, and with a brake 90. The brake is controlled by the arm 9| which is actuated by the link 92 carried by the lever 85. A spring 93 is interposed between the thrust member 94 on the link and the arm 9i.

To prevent overrunning of the shaft 1i it is provided with a friction drag designated generally by the numeral 95. The metal strip element 2 is passed over the support 96 with which the microswitches 91 are'associated so that in the event of the breaking or runningout ofthe strand 2, the switches are actuated to stop the 'through the cable indicated at |0| (see Fig. 2).

The complete binding tape is passed through the winding guide |02 to the reel |03 which is driven through the chain |04 and suitable sprockets. The Winding guide |02 is carried by an arm |06 which is pivoted at |01 and operavtively associated with a cam |08 which is connected by the sprocket chain |09 and suitable gears to the winding reel shaft ||0.

I have not illustrated and described various details as they form no part of my present invention and some of them are detailed in the aforementioned Boersma and Robinson patent, this invention being, as stated, an improvement upon and an adaptation of certain features disclosed in the aforesaid patent and in the copending application for patent of Boersma and Robinson, Serial Number 89,058, filed April 22, 1949.

I have illustrated and described the invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe certain embodiments and adaptations which I contemplate as it is believed that this disclosure will enable those skilled `in the art to embody or adapt the invention as may be desired.
