Abstract
Aspects herein are directed to a tensioning device for a strand on a knitting machine. The tensioning device includes a mounting plate that may be positioned between a strand source and a feeder bar. The mounting plate supports a first pulley, a second pulley and a weighted third pulley that is movable with respect to the first pulley and the second pulley. By routing a strand over the first pulley, under the third pulley and over the second pulley, additional tension may be added to the strand through the weight of the third pulley.
Claims20
A knitting machine, comprising:
- a strand source;
- a feeder bar;
- at least one strand extending from the strand source and through the feeder bar;
- and
- a tensioning device for the at least one strand, located between the strand source and the feeder bar, the tensioning device comprising:
- a mounting plate having an upper end, a lower end, a first side, and a second side spaced farther from the feeder bar than the first side, wherein the mounting plate comprises a slot;
- a first pulley coupled to the mounting plate;
- a second pulley coupled to the mounting plate and spaced from the first pulley;
- and
- a third pulley movably coupled to the mounting plate between the first pulley and the second pulley, and positioned at least partially below the first pulley and the second pulley,
- wherein the at least one strand is routable over the first pulley, under the third pulley, and over the second pulley, and
- wherein the movable coupling of the third pulley to the mounting plate allows a movement of the third pulley in a direction between the upper end of the mounting plate and the lower end of the mounting plate.

A knitting machine, comprising:
- at least one strand extending from a strand source and through a feeder bar;
- and
- a tensioning device for the at least one strand, located between the strand source and the feeder bar, the tensioning device comprising:
- a mounting plate having an upper end, a lower end, a first side, and a second side, wherein the mounting plate comprises a slot;
- a first pulley coupled to the mounting plate;
- a second pulley coupled to the mounting plate and spaced from the first pulley;
- and
- a third pulley movably coupled to the mounting plate,
- wherein the third pulley is movable between a plurality of fixed positions along the slot to thereby selectively adjust tension on the at least one strand.
