Abstract
Continuously connected fastener attachment stock formed by elongated plastic side members with cross coupling links. One of the side member has successively connected cross bars with each cross bar connected to one of the cross links. The other side member has successively connected head pieces with each head piece connected to one of the cross links. The stock is proportioned to be fed as an entity to a position within a machine where individual fasteners are sparated from the stock, with each separate fastener including a head piece, a cross bar, and coupling link interconnecting the head piece with the cross bar. Each cross bar is configured for feeding through the bore of a slotted hollow needle.

Fastener attachment stock comprising two continuous and elongated plastic side members that have cross coupling links;
- said stock being proportioned to be fed as a unit to a position where individual fasteners are separated therefrom within a machine;
- one of said side members being proportioned so that each separated fastener includes a bar formed from a portion of the side member and is configured for feeding through the bore of a slotted hollow needle;
- the other of said side members being proportioned so that each separated fastener includes a head member formed from a portion of the side member;
- and each cross link being foldable towards the associated end bar that is feedable through said hollow needle.
The method of providing individual fasteners from fastener stock comprising the steps of
- (a) Feeding fastener stock formed by two continuous and elongated plastic side members that are cross coupled by a plurality of cross links;
- (b) Separating an individual fastener from the fastener stock to provide a cross link with one end bar formed from a portion of one of said side members and an opposite end bar from a portion of the other of said side members;
- (c) Feeding at least one of the end bars through the bore of a hollow needle having a longitudinal slot for the passage of the associated cross link.
