A fastener (35) of the gripper (7) is mounted to the side of the reed (6) in eccentrically offset manner to the guide element (17).

Abstract: A receiving gripper for a rapier loom. The gripper includes a hook (3) and a clamping element (5) cooperating with the hook. The clamping element (5) is guided along a curved guide path (13) between an open position and a clamping position by a guide (14, 15) along a curved guide path (13). The guide path is directed to the hook's clamping surface (4) when in the zone before the clamping position and when in the zone of clamping position including a section in which no transverse displacement is superposed on the motion of the clamping element (5).

Abstract: A weaving machine air supply block (1). The air supply block includes conduits (8 through 13) and switched and/or adjusted valves (14, 15, 16, 17) driven by valve drives (14, 15, 16, 17) configured between an inlet (2, 3) and an outlet (5, 6). The device provides two outlets (5, 6) at one longitudinal side (7) of a substantially right parallelipipedic housing, each outlet being associated with its own valves (14, 15; 16, 17).

Abstract: A gripper weaving machine with a plurality of guiding devices(28) for guiding gripper carrying rapiers (1,2). The guiding devices (28) have two rows of guiding elements (35,36) with two guiding surfaces (37,38) that are associated with the bottom side of the rapiers (1,2). The guiding elements (35,36) are oriented relative to the bottom side of the rapiers (1,2) such that they form, at the side facing the reed (13), obtuse angles (B,B′,C,C′) with the bottom side of the rapiers (1,2).

Abstract: A method and apparatus to monitor filling insertion in a weaving machine. A filling (3, 4) is severed during insertion by a filling-scissors (15), and the actual time at which the filling (3, 4) is severed is detected.

Abstract: A drive for a mechanical loom. The drive includes a main drive shaft (2) that is mounted in a machine frame (1) and is driven by a drive motor (5) which is disposed coaxially to the main drive shaft (2) and directly connected thereto. The main drive shaft (2) is preferably designed as a motor shaft for the drive motor (5).

Abstract: An apparatus for tensioning warp threads in a weaving machine having a rotatably mounted carrier beam (5) which exerts strain on a tensioning roll (10) acting on the warp threads (15). A pre-stressed torsion spring (16) is arranged inside the carrier beam (5) and via its torque, presses the tensioning roll (10) against the warp threads (15). The apparatus can sense the torsional moments of the torsion spring (16).

Abstract: A gripper weaving machine with at least one gripper (1, 2) joined by a guide portion (21) to a rapier (3, 4) and fitted with guide units (19) arranged in a row and insertable into a formed shed (22). The guide portion (21) on its side facing away from the gripper (1) includes at least one slide rib (26) extending along the longitudinal direction of the guide portion and protects the warps (24) from making contact with the guide portion (21).

Abstract: A tubular housing is used for a gripper-loom's feed gripper. The feed gripper includes a metallic tubular housing formed of a single bent metal plate. The single bent metal plate includes at least two mutually overlapping segments that are rigidly joined to each other.

Abstract: A rotatable element (10) is configured with a helical, endless thread guide passage (14) which is used to twist at least two threads (8, 9), particularly in a weaving machine's selvage forming device (7). The threads (8, 9) are guided in the passage (14) and displaced axially and mutually crossed by rotating the rotatable element.

Abstract: A filling insertion system for a weaving machine includes a holder (8) for at least two nozzles (10, 11, 50). Each of the nozzles (10, 11, 50) includes a feed connection (20, 21, 52) for a pressurized fluid. The feed connections (20, 21, 52) are all arranged on the same side (15) of the holder (8) and are space apart from each other along the direction of the longitudinal axes (30, 31, 54) of the nozzles (10, 11, 50).

Abstract: A selvage insertion apparatus (13) for a weaving machine with at least one insertion arm (18) and at least one filling thread clamp (17) which can be applied through a drive device to control a filling thread and which operate from a common drive shaft (40). An individual drive motor (61) is operated by a programmable control system (14) and powers the drive shaft (40).

Abstract: A gripper-loom drawing gripper for receiving a yarn supplied by a yarn feeder and resting on a deflection guide, the gripper serving to position the yarn and carry it into the shed. The drawing gripper is configured to define a longitudinal cavity extending from its forward end facing a filling to be received and positioned by the gripper to its opposed rearward end. The cavity of the gripper faces towards and partially encloses the deflection guide. The forward tip of the gripper includes an inclined surface for guiding a filling to a positioning device on the gripper, and a yarn clamp is also carried by the gripper. The gripper includes additional receiving and positioning devices for a filling to be inserted in the loom shed.
