A drive platform assembly is provided for attachment to the carriage of an existing manually-operable fabric spreading machine to convert the machine to motorized operation. The drive platform is connected to the fabric spreading carriage of the fabric spreading machine and includes a drive motor which drives the drive platform in both a forward and reverse direction thereby enabling the carriage to spread successive layers of fabric onto a cutting table. This motion of the drive platform is guided by guide wheel assemblies which cooperate with a guide track mounted on the cutting table. This apparatus includes a speed control and a pair of cam assemblies which automatically reverse the direction of travel of the drive platform and the fabric spreading carriage at the end of each spreading stroke. The drive platform assembly includes a platform upon which an operator may stand to regulate the speed of the fabric spreading carriage, and also to observe and regulate the spreading operation.
A drive platform assembly for a fabric spreading machine having a fabric spreading carriage mounted on a cutting table, said drive platform assembly comprising platform means disposed adjacent said fabric spreading machine, drive wheels mounted on said platform means, electrical drive motor means mounted on said platform means, driving connection means connecting said drive motor means and said drive wheels, electrical connection means for connection of said drive motor means to a source of electric power, control means for controlling starting, stopping and reversing motion of said platform means, and connecting link means connecting said platform means and said fabric spreading carriage thereby enabling said platform to drive said fabric spreading carriage.
