An apparatus and method in which loose thread ends are drawn by air flow into a tube adjacent the needle of a sewing machine, at least between sewing operations.

Thread end holder for sewing machine

A needle cooler for a sewing machine with a vortex tube producing a cold air and hot air stream, a mounting block for mounting the cooler on a sewing machine with a bore connected to the vortex tube for transmitting the cold air to a nozzle via a flexible plastic tube, and an L-shaped positioning rod extending through bores in the block and nozzle for positioning the nozzle in a desired orientation with set screws engaging the rod in the bores for holding the nozzle in the desired orientation.

Needle cooler

An apparatus for removing both cut threads and trimmed edges from the working area of a sewing machine with a unit having a first air passage coupled to the area for removing trimmed edges, a second air passage coupled to the area for removing trimmed edges and opening into the first passage at an acute angle in an elliptically shaped opening to inject an air stream into the first passage to transfer momentum and cause air flow, the second passage comprising two tubular members one inside the other with the outer opening into the first passage, and a third air passage injecting air at a pressure above atmospheric pressure at an angle in an elliptically shaped opening to transfer momentum and create air flow through said second passage.
