Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a special die changing trolley for sewing machines. Background Art

[0002] The stitching machine is an important equipment in the color coating line. It stitches the head and tail of the strip steel when the steel coil is replaced to ensure the continuous operation of the production line. The mold of the stitching machine is a precise assembly.
