Abstract: A reed drive of a loom includes a reed shaft connected to a reed. A conversion gearing having an input element and an output element is provided at each end of the reed shaft. The input elements are coupled to driven shafts of electromotive rotary drives to produce a common rotational motion with the same rotational speed as the driven shafts. The conversion gearings convert the rotating motion of their input elements into a reversible rotation of the output elements, and the output elements are coupled to the reed shaft in a rotationally fixed manner. Thus, the number of complete rotations of an input element is equal to the number of complete motion cycles of the reed shaft per unit of time.

Abstract: The present invention provides a method for manufacturing a fabric and an apparatus for manufacturing a fabric that enable weaving of weak fibers including monofilaments of noble metal such as 24-carat gold.

Abstract: A terry weaving method and a terry loom for carrying out the method. Subject matter of the terry weaving method is that a slay travel shortening does not result during the carrying out of partial beat-ups for the formation of a weft thread group, and thus the original weft thread insertion window remains maintained. The terry loom has a servo drive (7) that displaces the reed support shaft (4) in the direction of the shed forming means by at least the pre-beat-up distance (VD) while maintaining the basic stroke H of the reed (11) before the forming of the weft thread group, and that reverses or undoes the displacement by at least the pre-beat-up distance (VD) after the forming of the weft thread group.

Abstract: The sley shaft of a loom, particularly a loom for weaving terry cloth or pile fabric, is rotated so as to provide more time for a gentle beat-up of the weft along the fabric beat-up line. For this purpose, the acceleration of the sley shaft and thus of the reed, which is connected to the sley shaft, toward the beat-up position is first faster to provide more time for the following entrainment of the weft or a group of wefts and for their beat-up by way of a discontinuous deceleration of the sley shaft and reed by a two phase deceleration toward the beat-up line. The two phase deceleration is interrupted by a slower deceleration between the two deceleration phases or by no deceleration between the two deceleration phases. Weft entrainment takes place between the two deceleration phases.

Abstract: A sley drive for a loom has a shaft which is eccentric to an axis of rotation in order to provide partial weight balancing for the pivoting movement of the sley. Sley levers are mounted on the sley shaft with each having a clip-shaped part for clamping about the shaft by a screw which passes through legs of the sley levers on the side of the reed relative to the axis of the rotation. Intermediate bearings may also be secured to the sley shaft in the same manner as the sley levers.

Abstract: A sley drive for a large power loom is comprised of a toggle joint moved by a complementary cam drive and linked on the one hand to the machine frame and on the other hand to the sley support. The toggle joint is folded when the reed beats against the fabric. In order to save space, the complementary cam drive and the toggle joint are arranged below the sley support, and the toggle joint engages the sley support below its pivot point. The arm of the toggle joint linked to the sley support is designed to be foldable about an intermediate pivot point and the pivot point is guided along a cam. The cam is adapted to be turned away from quick shut-down and a shock absorber is moved into engagement with the arm at the point where the toggle point is linked to the sley support.

Abstract: A reed operating system for a loom of the type wherein the advance position of a reed is altered. The reed operating system is comprised of a generally V-shaped swingable link through which the movement of a crank is transmitted to a sley sword to make swinging motion of the reed. The swingable link is rotatably mounted on and swingable around a pivot shaft which is mechanically connected to a hydraulic cylinder. The hydraulic cylinder so operates as to shift the position of the pivot shaft in a predetermined distance in a predetermined direction in accordance with a predetermined pattern, thus altering the advance position of the reed while hardly altering the backdown position of the reed.

Abstract: A fabric which contains warp threads made of a delicate material is produced on a loom which includes a main reed and auxiliary end reeds at opposite ends of the main reed and which are independently operable with respect to the main reed. The warp threads made of delicate material are extended through the main reed and warp threads of a more robust material are extended through the auxiliary end reeds. As each filler (weft) thread is inserted in a shed the auxiliary end reeds are moved to beat the associated portions of the weft threads. Only after a plurality of weft threads have been inserted is the main reed moved to beat the associated portion of the weft threads, thereby reducing the frequency of movement between the dents of the main reed and the delicate warp threads and thereby reducing frictional destruction thereof.
