ABSTRACT:
A method and apparatus for forming the mounting portion of a sidewall protector includes a rigid mold (19) in which a sidewall protector (12) can be formed and a separate plate assembly (29,31) which is moveable toward the rigid mold to form the mounting holes (10), central opening 11, and a pair of annular ribs (14,16) on opposite sides of the sidewall protector. Movement of the plate (32) is done by a plurality of springs (47) each positioned between the plate (32) and an enlarged head portion (48) of a pin (46). The springs are compressed by a linear actuator (43) and the pin (46) is connected to the mold (19) by a dowel (54) inserted through a hole (53) in the pin (46) to maintain the compression on the springs (47) . This apparatus permits the use of automated strip applying equipment for laying up the sidewall protector within the mold (19) while the plate assembly (29,31) accurately forms the mounting portion which includes the mounting holes (10), annular opening (11), and the annular ribs (14,16).
