Abstract
Abstract A machine for automatically stuffing a sleeping bag batting into an empty ticking. The machine comprises a reversible carriage which is adapted to receive a cut-to-length batting from a feed conveyor and carry it into an empty ticking with the carriage contacting the closed end of the ticking stretched over a funnel which receives the batting in such a fashion that the ticking is pulled inside out to cover the batting. After carrying the batting into the ticking, the carriage is reversed to receive another batting length. A stuffing conveyor is designed to transfer the batting from the feed conveyor into overlying relation with the carriage which is elevatable in its battingreceiving position to take the batting off the conveyor and then transfer it into the ticking. The stuffing conveyor is controlled to move the batting at a greatly faster rate of speed than the feed conveyor in order to provide ample time and space for working. Special control means comprising a timer disc or wheel is synchronized with the speed of the feed conveyor to operate the carriage and the supplementary stuffing conveyor with means for adjusting the control or timer disc to accommodate different lengths of batting. Limit switch control means are further provided for reversing the carriage and stopping it for the next batting-receiving operation.
