Abstract
Abstract Apparatus for automatically manufacturing an annular ribbon from stock as, for example, from a reel or roll of such ribbon. A feeding device cuts a length of ribbon dependent upon the preselected size of the annular ribbon, and the apparatus includes a pair of grip members which selectively hold the ends of the ribbon both during the formation of the loop and while the ribbon is being cut from the stock. The grip member rotates so as to cause the two free ends of the ribbon to overlap, thereby permitting the free ends to be secured together as by sewing.

Claim 1
Independent Claim
206 words
Apparatus for the automatic manufacture of an annular ribbon of predetermined size from a continuous stock of such ribbon comprising in combination, a pair of ribbon grip members being rotatable but fixed in translation, grip actuating means for selectively opening and closing said grip members, means for feeding the free end of the ribbon from the reel while said grip opening means holds both said grip members open, loop forming means effective when said grip actuating means holds open only the one said grip member which governs the feed of ribbon from the stock to feed said ribbon through said one grip member so as to form a loop therein of preselected size, means for cutting the ribbon between said one grip member and the reel after the formation of the loop in said ribbon, means for moving the grip actuating means out of engagement with first one and then the other of the grip members to thereby catch the free end of the ribbon and then the free end obtained after cutting, means for rotating both said grip members to thereby overlap the two free ends of the ribbon, and means for joining the two free ends of the ribbon to form a closed loop.
