Abstract
The present invention includes a sewing machine (12) with a variable top feed mechanism (25) that feeds the top layer of material for a sleeve at a variable rate to change the fullness thereof. The machine (12) is driven by a motor (42) which is controlled by a controller (51). A program is taught to the controller (51) for storage therein. The controller (51) then controls both the motor (42) and a controller (45) for the top feed mechanism to regulate the number of stitches and the relative rates of speed for the top and bottom materials fed by the machine. The program initially is taught to the machine and can be utilized for any type of material or size by inputting the correct sizes and types of material on a control panel (44). The machine (12) therefore semi-automatically sews sleeves onto armholes with the correct fullness sewn therein.
