Abstract: An installation head adapted to receive a fastener for securing the fastener to a sheet metal member on actuation of the head by a press. The head includes a main block having a bore, a cylindrical press member disposed within and supported by the bore, the press member having an arrangement for receiving and holding the fastener, wherein the cylindrical press member is rotatable in the bore between a first position, in which the fastener is received by the arrangement for receiving and holding the fastener and held in position relative to the press member, and a second position for actuation of the press.

Abstract: A stud (1) for mounting a pulley (2) to a plate (3) by a cold forming process has a large diameter head (5), a cylindrical shank (6) which acts as the stub shaft for the pulley (2), the end of the shank remote from the head being connected to a smaller diameter shank (7) via a shoulder (9) (which may include an annual grove (10) into which the plate (3) is deformed), and, beyond the smaller diameter shank, an e.g. threaded shaft (8). To resist rotation after the stud (1) is cold formed to the plate (3), the stud (1) has ribs or studs or flat facets on the shoulder or on the narrow shank (7) against which the plate is cold formed.

Abstract: A feed head has a delivery path along which nuts are fed to a pressing station in the feed head, the pressing station having a pressing die which is reciprocated transversely to the delivery path under the action of a press to fasten a nut to a sheet metal member. A cam is provided to reciprocate the pressing die manually to facilitate clearance of blockages in the feed head, and also to hold the pressing die in its lowered position to allow operation of the press without operating the die. A sensor for detecting nuts at the pressing station is positioned on the end of the delivery path, enabling a narrower feed head design. A electrical coupling and nut delivery tube are integrated to facilitate connection in confined spaces.
