摘要:
A shaft transmission (3) for a weaving machine comprises a shaft arrangement (8) that supports, on one end, a crown wheel (10) in order to drive the shaft arrangement (8), which is supported by two bearing arrangements (12, 13), between which a package (28) comprising the cam disks (29-29i) is non-torsionally held on the shaft arrangement (8). The part (18) of the shaft arrangement (8), which supports the package (28), is connected with the remaining part (17) of the shaft arrangement (8) via a clutch arrangement (19), and is secured, in connected state, by a locking arrangement (41) that is actuated from one end of the shaft arrangement (8). For disassembly and replacement of the package (28), the connection can be released and the cam disk section (18) can be removed from the shaft transmission (3), while the drive section (17) remains in the shaft transmission (3).

A cam motion machine that includes several cams each defining at least one running track for a follower roller. Each cam is provided with a centering bore that permits mounting of the cam on a drive shaft, while elements are provided to apply a tightening force parallel to the drive shaft with a non-circular section. At least one washer-spacer, for which an internal edge is non-circular and designed to enable an axial displacement of the washer-spacer along the shaft, is fixed to rotate with the shaft and is in contact with at least one of the cams. The washer-spacer may be fixed to the cam by adherence and to the shaft by cooperation of shapes due to complementary projections provided on one of the shaft and the washer-spacer.It would be appreciate if the Examiner would indicate the acceptance of this amendment to the Abstract in the next office communication.

In a weaving loom, an assembly for controlling the reciprocating movement of the upper and lower frames of the shed-forming device which assembly includes a shaft of which the ends are each associated with the ends of two connecting rods by way of eccentrics and which connecting rods are articulated on rocking levers whose arms are pivotally associated with short and long levers attached respectively to the upper and lower frames of the shed-forming device.

In a circular loom provided with a main drive shaft, a plurality of healds are arranged in a ring-shaped alignment coaxially around the main drive shaft. An annular reed member is stationarily located inside the ring-shaped alignment of the healds and coaxially therearound, wherein shuttles are able to move along an annular passage defined by the annular reed member, a weft taken out from each of the shuttles is inserted to successive sheds created by a shed-forming mechanism and the inserted weft is interwoven with the warps to form a tubular fabric having a predetermined weave structure, by applying a particular shed forming mechanism based upon a principle such that the shedding operations of a unit group of warps to create each one repeat weave structure is controlled to satisfy the crossing condition between said warps and said inserted weft which is defined by said one repeat weave structure.

A loom includes a plurality of reciprocatably displaceable heald devices each generally disposed in a respective one of a plurality of parallel planes, and a plurality of levers each coupled through an intermediate element to a respective one of the heald devices. The respective pivot axis of each of at least two levers is differently spaced from the respective intermediate element to cause a respectively different displacement stroke for each of the at least two heald devices connected thereto. The respective pivot axis of each of the at least two levers is differently spaced from a plane which extends centrally of each heald device, parallel to the line of displacement thereof and perpendicularly to the planes of the heald devices.

The eccentric drive for lifting the heddle frame uses a mounting arrangement by which cam rollers can be detachably mounted on a cam-follower lever. The mounting arrangement uses a roller journal which is secured by bolts to the lever and which serves as a mount for a roller. The diameter of the journal surface on which the roller rotates is relatively large to provide a low surface pressure of the roller on the journal.

The present invention relates to a shedding drive arrangement for a loom, with a dobby driving the upper and lower sheds symmetrically and with a coupling arrangement coupling the rockers of the dobby with the weaving shafts to produce a non-symmetrical shed movement. By "rockers" or jack levers there are generally understood elements which transmit the driving movement produced by the dobby and available at its output side.

Dobby having cams of a varying ratio for looms, in combination comprising a rotary cam carrying drum, interchangeably carrying a plurality of cams, each of which through a cam follower means and a suitable spring return lever system operating a corresponding heddle carrying frame in the loom. The cams may be either disc cams or chain cams at the same time winding up on a second idle drum which can be moved to or away from the first drum to accomodate chain cams of a different length for operating said chain cams.

The invention relates to a shedding device for a weaving machine which consists of a rotatably operable cylindrical member formed of a series of parallel spaced-apart disclike sections; each section is adapted for rotational movement about a longitudinal axis and is provided with warp lifting portions extending for a predetermined arc about the axis. The disclike sections may be assembled on the axle in a variety of combinations in order to produce a great variety of patterns.
