Abstract
A pressure foot for minimizing puckering or bunching of biasing fabric and a cloth item, garment or quilt when being sewn or finished. The pressure foot includes a laterally displaced inner foot displaced from the inner feed dog of the sewing machine and a bias guide between the inner and outer feet. The pressure foot is adapted to be used alone or in combination with a bias binder sewing aid that automatically folds the biasing fabric. The pressure foot and bias binder sewing aid form a kit for sewing biasing fabric to an unfinished edge of a cloth item, garment, quilt or the like.

A pressure foot for use with a conventional sewing machine comprising:
- a base adapted to be mounted to a mount of the sewing machine;
- parallel inner and outer feet, the outer foot being substantially aligned with an outer feed dog of the machine and an inner foot laterally displaced from the outer foot and the inner feed dog of said machine;
- a bias guide formed between the inner and outer feet having a channel formed between interior walls of the outer foot and the inner foot and a joining top surface joining the inner and outer feet for feeding therethrough biasing fabric when sewing, said bias guide having a flared outlet;
- and,
- a needle and thread slot formed in the joining top surface and being generally “7” shaped and, wherein the joining top surface applies pressure to the biasing fabric underneath.
A bias binding sewing aid kit for use with a conventional sewing machine comprising:
- means for automatically folding biasing fabric into quarters and outputting the folded biasing fabric;
- and,
- a pressure foot having parallel inner and outer feet, the outer foot being substantially aligned with an outer feed dog of the machine and an inner foot laterally displaced from the outer foot and the inner feed dog of said machine and a bias guide formed between the inner and outer feet having a channel formed between interior walls of the outer foot and the inner foot and a joining top surface joining the inner and outer feet, said bias guide having a flared outlet;
- and,
- a needle and thread slot formed in the joining top surface and being generally “7” shaped and, wherein the joining top surface applies downward pressure to the biasing fabric underneath.
