Abstract
An apparatus for advancing limp material such as cloth for overedge stitching. The apparatus has a generally L-shaped arm which is designed to be pivotable in the lateral and upward directions relative to a surface of a working table of a sewing machine. The L-shaped arm has at least a single rotary element for advancing the cloth, the rotary element being driven through a driving pulley and an endless belt. The apparatus has devices for locking the lateral and upward movement against a resilient force of the endless belt.
Claims6
A guidance apparatus for a sewing machine having a variable-speed drive unit and a working table that permits overedge stitching said guidance apparatus comprising:
- a shaft rotatably connected to said variable-speed drive unit at one end thereof;
- a driving pulley connected to the other end of said shaft;
- an L-shaped member pivotally connected to said shaft;
- said L-shaped member being pivotable laterally and vertically relative to a plane of the working table of the sewing machine,
- pulley means rotatably connected to one end of said L-shaped member,
- a first means for locking the lateral movement of said L-shaped member,
- a second means for locking the vertical movement of said L-shaped member, said second means being positioned higher relative to the axis of said driving pulley when said second means and said pulley are in their positions of intended use, and
- endless belt means operatively connecting said driving pulley with said pulley means.
