Abstract: A method for making a collated fastener assembly includes arranging a plurality of fasteners in a row parallel to one another, in a plane, and spaced from one another, preheating the fasteners, applying a molten polymer material onto the fasteners and conveying the fasteners with the polymer into a mold cavity. The fasteners are maintained in the plane. The polymer is molded onto the fasteners and between adjacent fasteners to form a molding having a collar encircling a shank of each fastener and a connecting portion between adjacent fasteners. The molding maintains the space between the fasteners. A cooling stream is introduced onto the fasteners and the molding as the fasteners and the molding exit from the mold cavity.

Abstract: A slack adjuster for vehicle brakes is adapted to be mounted between the vehicle brake chamber and the vehicle brake operating shaft and includes a body which positions a drive member movable relative thereto on the brake operating shaft. A lever arm is pivoted to the body and there is an adjustable connection between the lever arm and the drive member for adjusting the relationship between the drive member and the body in response to body movement required for a brake application. The improvement herein is specifically directed to a device for connecting a brake rod to the lever arm and more specifically to a bushing threaded upon the brake rod and rotatably positioned within the lever.
