Abstract
A power loom selvage forming device includes at least two thread guide elements for guiding selvage threads. The thread guide elements are guided in longitudinal guides and are connected by transmission elements to a drive shaft driven by a drive motor. The axis of the drive shaft is perpendicular to the direction of motion of the thread guide elements, with the transmission element converting the rotations of the drive motor into longitudinal motions of the thread guide elements containing at least one element mounted on the drive shaft and including articulation points eccentric to the drive shaft and at a mutual angular separation. The drive motor is rotatable by a control into predetermined angular positions at predetermined times.
Claims16
A power-loom selvage forming device comprising:
- at least two selvage thread guides mounted for longitudinal reciprocal motion and selvage thread guide supports associated with relatively fixed loom structure arranged for guiding the motion of the selvage thread guides;
- a drive motor;
- and a drive shaft driven by the motor and extending perpendicular to the direction of motion of the selvage thread guides;
- transmission elements connecting each selvage thread guide to the drive shaft;
- said transmission elements arranged to convert rotary drive shaft motion to rectilinear selvage thread guide motion;
- said transmission elements each including at least a first portion secured to the drive shaft and at least a second portion secured to one of the selvage thread guides, each transmission element including an articulation point connecting the first and second portions, and each articulation point being located eccentrically of the drive shaft;
- said articulation points being spaced by an angle of separation and located at opposite sides of the drive shaft;
- and
- a control system for actuating the drive motor to cause predetermined angular rotations of said drive shaft at predetermined times to thereby cause timed shed forming motions of the selvage thread guides.
