Abstract
A heddle shaft (1) with heddles (3) that are supported with little play or free of play has at least one heddle support rail (7), which is supported movably for elastically tensing the heddles (3) as a whole, or has at least one movably supported part (55). A spring means (16, 56) serves to exert a tensing force on the heddle head (5) of each heddle (3) for supporting that heddle without play. This makes a high operating speed of a power loom, provided with such a heddle shaft, possible without the heddles digging into the heddle support rails and without producing excessive noise.
Claims8
A shaft frame, for power looms, having at least one heddle support rail, which is resiliently supported or has a resiliently supported portion, for receiving one or more heddles by extending into a single end eyelet of each heddle;
- and wherein:
- the at least one heddle support rail is supported in a stationary fashion on the frame and is formed as two support rail portions, embodied as resilient spring legs, pointing away from one another.
A shaft frame, for power looms, having at least one heddle support rail, which is resiliently supported or has a resiliently supported portion, for receiving one or more heddles by extending into a single end eyelet of each heddle;
- and wherein
- the at least one heddle support rail is formed of two diametrically opposed receiving jibs, which are tensed resiliently away from one another, in order to receive heddle heads without play by extending into a respective heddle end eyelet of a respective heddle.
A shaft frame, for power looms, having at least one heddle support rail, which is resiliently supported or has a resiliently supported portion, for receiving one or more heddles by extending into a single end eyelet of each heddle;
- and wherein
- the at least one heddle support rail is formed of two diametrically opposed parts embodied as receiving jibs for a single end eyelet of heddle heads, of which one jib is supported rigidly on a beam connected to the frame and the other jib is supported movably on the beam counter to at least one spring element.
