Abstract
A method and apparatus is disclosed for attaching a continuous tape to a circular edge of a tubular workpiece with a sewing machine, and cutting the tape so that an overlapping length of the tape tail end on the sewing front portion of the tape is of a uniform length for various kinds of workpieces without changing the preset conditions. The apparatus has a stitch counter, a tape cutter and a thickness detecting sensor of the light transmission type for detecting the presence or absence of thick materials in front a presser foot 2. In the tape sewing process, when the sewing front end makes a full turn and reaches the thickness detecting sensor and this sensor detects that the quantity of transmitted light is lower than a specific level, the stitch counter begins to count the number of stitches, and when the low level continues over a specific number of stitches, the tape cutter is actuated.
