Abstract
The cloth end position control apparatus for a sewing machine of the present invention functions to control the end portion of the cloth to a specified sewing position. A cloth end control roller corrects the position deviation of the cloth by rotating in a direction orthogonal to the cloth feed direction depending on the detection by a cloth end detector for detecting the end portion of the cloth C. A pressing member guides the end portion of the cloth C by gripping the cloth C against the cloth end control roller. The cloth roller is rotatable about a shaft disposed at the cloth feed-in side to the roller and in a horizontal direction orthogonal to the cloth feed direction, and is elastically thrust in a direction reverse to the cloth feed direction through a coil spring. When a step portion of the cloth passes through between the roller and the pressing member, the roller rotates about the shaft so as to separate from the member against the elastic thrusting force, depending on the thickness of the step portion.
