Obliquely cohered fasteners may be formed by adhering wires with an adhesive coating to form a strip. The strip is then shaped so that the wires are formed into fasteners of the desired shape. The adhesive coating is then plasticized and while plasticized, each fastener is offset from the next to obtain the obliquely cohered fasteners. Then, the adhesive coating is rehardened. Instead of applying a single adhesive coating, the wires may be adhered with a first thermoplastic coating and a second coating of a non-self-adhesive resin. The second coating may be applied only to that portion of the first coating covering the fasteners. Alternatively, as the fasteners are offset, the second coating may be cracked between fasteners to weaken the second coating, allowing the fasteners to be more easily separated when desired. The off-setting may be performed by a device which applies a force to one of the ends of the fasteners while the other of the ends of the fasteners are displaced. |
