CUTTING MACHINE Filed Nov. 29, 1943 2 Sheets-Sheet 2 IN VEN TOR.
Patented Dec. 31, 1946 UNITED STATES PATENT OFFICE CUTTING MACHINE Louis V. Lucia, West Hartford, Conn. Application November 29, rsiaserial No. 512,223
21 Claims.
This invention relates to cutting machines and more particularly to machines for cutting Venetian blind tape such as clearly described in my copending application Serial No. 445,213, filed May 30, 1942, now Patent No. 2,347,603.
The object of this invention is to provide improved and further simplified means for cutting the Venetian blind tape.
Other objects and advantages of the invention will be more clearly understood from the following description and from the accompanying drawings in'which:
Fig. 1 is a plan View of a cutting machine embodying my invention.
Fig. 2 is a side viewthereof.
Fig. 3 is a fragmentary plan view on an enlarged scale illustrating the operation of one of the cutting units of the machine.
Fig. 4 is-a view in vertical section on line 4-4 of Fig. 3.
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 indicated generally at8, for applying tensionto the tape, all of which is described in my abovementioned co-pending application.
In the form of my invention which is described 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 machine. 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. I
If desired, each set of cutters may be constructed sothat the disk member ill will have projections or blades l2 thereon each of which forms one blade of a scissors. The other blade of 2. clearly described in my co-pending' application, by positioning it. between the feed roll 6 and the tensioning mechanism 8. 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 between tension plates 8--a and 8--b. Duringthe movement of the tape, each set of cross threads in the tape is brought into. contact with oneof the extensions. 1.2 and thereby rotate the diskis so that. all of the scissors of the. unit are kept in mesh with the cross threads of the moving tape.
As each set of crossthreads, or straps, moves into engagement with theblade 12 of its corre" the scissors consists of a member I3 which is An operating cam member Hi is preferably mounted upon the post H and. is. adjustably'securedthereto by means of. a screw 25.
The operation of my improved cutting machine is. as. follows.
The tape. 1. is first placed in the machine, as
as it moves through the. machine...
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 tirely by the movement of the tape through the machinea-nd that no extra driving means is necessary for driving the cutting means.
, The cam Iliis stationary on the post i I but adjustable thereon,by means of the'screw 20, so that the said cam may be timed to cause the scissors tocl'ose when in proper position and while in engagement with the cross threads when they are disposed within the scissors. r v It will be clearly seen from Fig. 3 that,'just one group of cross-threads is being severed by'its corresponding scissor, the following scissor is ready to receive and be moved by the next group of cross threads; thus; continuous rotation of the scissor carrying disk. lilis maintained by the tape As; illustrated in Fig. 4, the scissor. carryin member Himay 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 post II, to provide the necessary amount of friction 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 scissors in proper contact with the cross threads as they are engaged thereby and the said threads are being cut by the scissors.
As shown in Fig. 3, the scissor may be construc-ted so that they each will include a plate 28 which carries the blades l2 and I3 thereon and is adjustably secured to the disk It! by means of screws 29-29 that extend through slots 3ll30 in said plate. The cam 19 may be made adjustable by means of an extension plate 3| secured to a projecting portion 32 on the hub 2B by a screw 33 that extends through the slot 34. This construction will permit radial adjustment of the scissors for varying the spacing between them in accordance with the spacing between the cross threads of different sizes and types of tapes and thereby permit the use of the same cutting unit on difierently spaced cross threads. It will be understood that the cam 19 may be adjusted for the lengths required to operate the scissors in their different positional adjustments. Lateral adjustment of each scissor unit, so that the blades l2 and 13 will project for the proper distance into the tape, may be made by sliding the support 35 on the bed and securing it in proper position by means of the screw 36 which extends through the slot 31.
