Abstract
Abstract A sewing machine apparatus for sewing an elongated cloth strip onto a piece of cloth in a generally U-shaped configuration includes a sewing machine having a foot and a vertically reciprocal needle guided by the foot. A cloth strip guide is rotatably supported by the foot about the vertical axis of the needle and includes a slot for guiding the cloth strip below the needle. A cloth clamp assembly with inner and outer U-shaped clamp members pivoted to each other at their open ends is movable to a clamping position to clamp the piece of cloth and leave an edge thereof exposed for sewing. The cloth strip guide slidably engages the inner clamp member during relative movement between the sewing machine and the cloth clamp assembly in the U-shaped configuration in which the cloth strip is to be stitched. This sliding engagement controls the rotational position of the cloth strip guide with respect to the sewing machine foot so as to thereby guide the cloth strip as it is stitched to the exposed edge of the piece of cloth.

Claim 1
Independent Claim
232 words
A sewing machine apparatus for sewing an elongated cloth strip onto a piece of cloth in a generally U-shaped configuration, the apparatus comprising, a sewing machine including a foot and a vertically reciprocal needle guided by the foot, a cloth guide for guiding the cloth strip below the needle, means rotatably supporting the cloth strip guide on the foot about the vertical axis of the needle and the cloth strip guide having a slide portion, a cloth clamp assembly including a pair of generally U-shaped clamp members connected to each other at the open ends thereof so as to be movable between a nonclamping position and a generally coplanar clamping position, the piece of cloth being clamped between the clamp members in the clamping position so as to leave an edge thereof exposed for sewing, and a U-shaped slide surface on the clamp assembly which is engaged by the slide portion of the cloth strip guide during relative movement between the sewing machine and the clamp assembly in the U-shaped configuration in which the cloth strip is to be stitched to the piece of cloth, this engagement controlling the rotational position of the cloth strip guide with respect to the sewing machine foot so as to thereby guide the cloth strip as it is stitched to the exposed edge of the piece of cloth within the Ushaped configuration of the clamp assembly.
