Abstract: 911,595. Shearing. FRANKLIN RESEARCH & DEVELOPMENT CORPORATION. April 25, 1961 [Nov. 4, 1960], No. 14936/61. Class 83 (4). [Also in Group IX] In a continuous stock winding apparatus, Figs. 1 and 2, stock s, e.g. insulated wire or cable, is wound over axially aligned reels R removably mounted on spindles 24 which are rotated by means of power-driven belts 42 through pulleys 44 secured to the spindles, and is crossed over under tension from wind-on rotation with one reel to the other by means of a guide 50, the cross-over stock between and taken around by the rotary reels R being severed by a cutting device 62, Fig. 4, having two rotary discs 64 with peripheral shear edges 66, the bite b of which lies in the path of the cross-over stock. Each spindle 24 is carried in a stand 22 which is pivoted on a frame bar 16 by means of a pivotable cylinder 36 into its raised reel-winding or lower reel-exchange position. In the winding position the pulley 44 is brought into contact with the belt 42. The guide 50 carries a pair of rotary guide rolls 54 between which the stock s is fed in successive layers on to one reel as the guide is reciprocated on a frame bar 20 by means of a threaded drive-spindle 55. When the reel is fully wound, the spindle 55 quickly shifts the guide 50 into winding relation with the adjacent empty reel causing the carryover stock to spin around with the reels owing to its firm contact with their flanges f. The cross-over stock is severed by the cutting device 62 after a few turns of stock have been wound on the empty reel to hold it securely. The stand 22 with the fully-wound reel is then lowered and the reel is replaced by an empty one which is raised back to the winding position in time to be driven by the belt 42 and to receive stock from the guide 50 so that continuous winding is maintained. The discs 64 of the device 62, Fig. 4, are rotatably mounted, with their shear edges 66 in a common plane p, on studs 70 secured in a support 68 which also acts as a safety guard over the discs. One of the studs 70 is eccentrically arranged with respect to its shank 72 so that angular adjustment of the shank in the support 68 varies the spacing of the edges 66 at their bite b. The support 68 is bolted to an arm 80 on one end of a shaft 82 on the other end of which is an arm 86 pivotally connected to the piston rod 88 of a cylinder 90 pivotally mounted on an arm 94 fixed on a frame bar 18. The device 62 is projected in the path of the cross-over stock by providing pressure fluid to the cylinder 90 which is subsequently vented to allow the device to return to its inoperative position under the action of a compression spring 96 mounted on the rod 88. Shoulders 100 on the support 68 on opposite sides of the discs 64 and spaced from their bite b are provided to ensure complete separation of any cross-over stock which may not have been completely severed by the shear edges 66. The support 68 is formed with slots 104 having flared edges 106 to provide a wedge-like guide for the cross-over stock. In a modification, the cutting device is fixedly mounted in the path of the cross-over stock in an apparatus in which the reels are on their adjacent flanges provided with anchor devices which snatch and securely hold the cross-over stock the moment it comes within their reach.
