ABSTRACT:
An adjustable motion control apparatus for fabric spreading machines includes a track which is attached to an edge of the table on which the fabric spreading machine deposits layers of fabric. A pair of blocks are slidably mounted on the track and a rail member is mounted on the pair of blocks. An end of the rail member includes a cam surface which actuates a switch on a carriage assembly of the fabric spreading machine to decrease the traverse speed of the carriage assembly. A cam block is mounted on the rail member and actuates a second switch on the carriage assembly which reverses the direction of traverse of the carriage assembly. When it is desired to adjust the motion of the carriage assembly to vary the length of the fabric being deposited, the operator need only loosen a pair of set screws on the blocks, slide the rail to a new position relative to the table and retighten the set screws.
