Abstract
A device for marking the height above the floor of the edges of articles of clothing in which a force accumulator is charged and released upon actuation of a cloth-pressing lever which drives a pin into the cloth from a pin magazine.
Claims24
In a device for marking the height above the floor of the edges of articles of clothing, having a fabric deflector with a deflection slot and a longitudinal channel transverse to the deflection slot, and a fabric pressing lever which is movable into the deflection slot, the fabric pressing lever having an immersion end portion with a recess which is alignable with the longitudinal channel of the fabric deflector, wherein the improvement comprises
- a pin magazine shaft extending transversely of said channel and communicating with said channel, and
- a pin insertion ram movable in said channel, and
- actuating means operatively engageable with said pin insertion ram for automatically actuating movement of said pin insertion ram,
- a first movable carriage member supporting said pin insertion ram, said first movable carriage member having a release step,
- said actuating means, comprising a force accumulator means for acting on said first movable carriage member and for accumulating force with which to move said pin insertion ram, for charging said force accumulator means upon a swinging-in movement of said fabric pressing lever and for operatively releasing said force accumulator means via said release step in an end phase of the swinging-in movement of said fabric pressing lever so as to move said pin insertion ram.
A device for marking the height above the floor of the hem of fabric garments, comprising:
- means for deflecting said fabric,
- means for receiving said deflected fabric, and
- means for respectively inserting pins into said fabric where each pin insertion is imparted with an equal amount of force, said means for inserting further comprises
- a first movable carriage member,
- a pin insertion ram supported on said first movable carriage member,
- means for accumulating a force and for suddenly releasing said force when a predetermined amount of force has been accumulated so as to move said first movable carriage member.
