ABSTRACT:
Adjustable roller frame includes a body member and clamp member having laterally spaced apart grooves in opposing surfaces thereof which cooperate to define a pair of laterally spaced generally parallel guideways for sliding receipt of a pair of roller support arms. The arms are made of metal tubing bent into a generally L-shape including a short leg and long leg. Each long leg is deformed from opposite sides over a portion of its length to form a pair of relatively sharp corners extending the length of the deformed portion while generally maintaining the radius of the tubing between the corners to minimize internal stresses in the tubing. Between the corners and normal tube radius is a radiused transition area. The cooperating grooves in the body and clamp members have a combined shape generally corresponding to the deformed shape of the long legs of the arms and include notches which receive the corners on the arms for supporting the arms against rotation while permitting relative axial sliding movement of the arms in the grooves. The notches in the body member are spaced further apart than the notches in the clamp member to cause a towing in of the short legs to bring roller end mounts on the short legs into coaxial alignment with each other.
