The two strips of the Venetian. blind tape are then separated and the cross» threads or straps, indicated at. 21, which are to be cut in the machine; are placed inmesh with the projections. l2 of the scissor units so that the scissors, or cutters, are actually geared to the cross threads as clearly illustrated in Fig. 3. The, tape: is then moved through the machine. by the feed rolls 6-6 which are driven by the motor indicated at 22 and pull the tape through the machine against the tension applied thereon be tween tension plates 8--a and 8--b.

' 2.0 , As illustrated in the drawings, my» improved machine comprises a bed 5 having thereon the cutting mechanism which includesfeed rollers 6-—-6, for feeding the tape 1. through the machine, and a suitable tensioning mechanism, as indi cated generally at‘8, for applying tensionto the tape, all of which is described in my abovemen tioned co-pending application. . ‘ In the form of my invention which is de scribed herein, I provide a plurality of, cutters in. the form of scissors 9 which are carried on a disk, or frame, In thatis rotatably mounted on a post ll upon the bed 5 and adjacent to the side of the tape 1 as it is moved through the ma chine. A similar set of cutters is mounted on the other side of the tape ‘I so that both sides of the tape may be cut at the same time. 2. clearly described in my co-pending' application, This invention relates to cutting machines and more particularly to machines for cutting Vene tian blind tape such as clearly described in my co pending application Serial No. 445,213, ?led May 30, 1942, now Patent No. 2,347,603. The object of this’ invention is to provide im proved and further simpli?ed means for cutting the Venetian blind tape. Other objects and advantages of the invention tape. \ As each set of crossthreads, or straps, moves - into engagement with theblade 12 of its corre" sponding scissor and rotates'the disk H], the stud M3 on the extension It? will engage the cam I9 . and thereby cause the scissors to close and cut the'croiss threads as it is movingtherewith; see Fig. 3.. After the cross‘ threads have been cut and the scissors has moved. out of engagement with the cam I 9, the spring I‘! will again open the scissor so ‘that it will be ready to receive its next corresponding cross thread as it is carried past the tape by therotation of the disk Hi. It will be understood, from the above descrip tion, that the‘ cutting mechanism is operated en tirely by the movement of the vtape through the machinea-nd that no extra driving means is neces sary’ for driving the cutting means. I If desired, each set of cutters may be con , The cam Iliis stationary on the post i I but ad forms one blade of a scissors. The other blade of tocl'ose when in proper position and ‘while in en~ justabl‘e thereon,by means of the'screw 20, so that structed sothat the disk member ill will have projections or blades l2 thereonleach of which 40 the said cam may be timed to cause the scissors ' the» scissors consists of a member I3 which is . gagement with the cross threads when they are pivoted as at M on said member ID. disposed one It group will be within ofclearly cross-threads the seen scissors. from is being Fig. 3. severed that,'just r v by'its Each. of the said. blades I3 is- provided with. an extension l5 having a stud I6 thereon. A. spring 40 corresponding scissor, the following ‘ scissor is I‘! is provided for retaining the scissor in open ready. to receive and be moved by the next group position by urging the. extension l5 against a of crossithreads; thus; continuous rotation of the stop pin I8 which. is mounted on the disk H) as scissor carrying disk. l‘il‘is maintained by the tape clearly shown in the drawings. An ‘operating cam member Hi is preferably ' mounted upon the post H and. is. adjustably'se curedthereto by means of. a screw 25. . The operation of my improved cutting machine is. as. follows. ‘ The tape. 1. is ?rst placed in the machine, as ' as it moves through the. machine... As; illustrated in Fig. 4, the scissor. carryin member Hi- may be mounted: to be‘ positioned ‘be-' tween the‘ hub; 25’ of. the earn [9. and the disk‘ It and it'may be adjusted for the proper ten. sion. by. vertical. adjustment of. the cam onthe 2,413,511 I I 3 4 post II, to provide the necessary amount of fric to operate each of said cutters while in motion tion against the rotation of the disk H) to prevent the scissors from running ahead of the cross threads in the tape and thereby keeping the and at a pre-determined position. 6.
