摘要

Trackless gantry press apparatus (10) are disclosed. The gantry press apparatus (10) includes, in one embodiment, a plurality of truss setup tables (14) configured to form a row of spaced truss setup tables (14). Each table (14) includes wheel guides (22) coupled at opposing ends (16,18) and extending the width of the table (14). The guides (22) are configured to be in substantial alignment with the guides coupled to adjacent tables (14). The apparatus also includes a press assembly (12) for pressing nailing plates into truss members. The press assembly (12) includes a substantially cylindrically shaped roller (34) movably coupled to a substantially inverted U-shaped frame (30). The press assembly (12) also includes at least four support wheels (36) and at least four reaction pressure wheels (38) coupled to each opposite end of the frame and configured so that at least three support wheels (36) on each end of the press assembly (12) are in contact with the wheel guides (22) at all times as the press assembly (12) traverses the spaces between the spaced setup tables (14). Additionally, a motor (32) is operatively coupled to the roller (34) and the drive wheels (36) and configured so that the roller (34) and the drive wheels (36) rotate at the same speed.
