The gripper loom has picking tapes and rapier heads whose centers of gravity are disposed above the top of the tape. Between the tape wheels and the shed, tape guides are provided to impart to the picking tapes an inclined direction of movement towards the shed. Due to these inclined tape guides, disengagement of the rapier heads from the raceway in the shed can be obviated, with a consequent reduction in the frequency of warp yarn breakages.

The tuck-in needle of a mechanical selvedge-forming device has a catcher for a yarn end following a needle tip. The catcher is subdivided into an entry zone and a trough screened from the entry zone by a hook disposed towards the trough. In its catching movement the needle is moved only towards the weft yarn so that the yarn moves into the entry zone of the catcher. The weft yarn then slides inclinedly over the outside of the hook until passing by way of the hook tip into the catcher interior. The weft yarn can be drawn into the cloth selvedge in this position. This construction enables the tucking-in to be very simple.

The pacing motion which is adapted to be stepped on in respect of individual wefts has a sliding wedge with a return spring. The wedge is displaceable on an output shaft into a groove of an input shaft in both directions of rotation. The motion also includes a locking lever actuatable off-load by a control signal. The lever locks and unlocks a release lever which is driven by a drive element and actuates the wedge. A transmission with a delay feature or a resilient damping insert can be used as an impact-reducing element to absorb some of the impact of the wedge in the groove. Freely actuatable electromagnets can be used both as actuating elements and as the drive element.

The yarn selector comprises a number of yarn regulators each adapted to be selectively adjusted by way of a driving member between a standby position and a transfer position in dependence upon an actuator in which transfer position, a weft yarn is presented to a picking element for a subsequent pick. The driving members are selectively engageable with and disengageable from a driver oscillated at the cadence of the picking fequency. Each driving member is adapted to be locked, with the actuator in an active state by way of a ever-arm in an operative position corresponding to the transfer position of the yarn regulator, and to be disengaged from the lever arm with the actuator in a passive state. The particular yarn regulator concerned remains, if the same weft yarn is required for the next pick, in the transfer position after yarn transfer and is returned to the standby position only before a weft yarn change.

A device for maintaining an insertion band against an oscillating insertion band wheel by providing a flexible element which is movable in oscillating fashion in synchronism with the insertion band and rests from the outside against the insertion band under an initial stress.

A withdrawing carrier for looms with removal of the filling thread from stationary bobbins, the carrier having a hook and a pivotal clamping tongue. An additional clamping element is provided for augmenting the clamping action exerted by the clamping tongue upon the filling thread.

A total ankle prosthesis is formed of two parts, the upper part of which has a concave lower surface in saggital section while the lower part has a convex upper surface in sagittal section slidingly guided on the upper part. Each of these surfaces is of wave form in frontal cross-section with one surface having a raised central portion while the other has a guide groove receiving the raised portion. The side walls of the upper part extend downwardly past the bottom surface of the lower part to protect and avoid excess rubbing of the bottom ends of the tibia and fibula on the bottom part of the prosthesis and to discourage scar tissue between the surfaces.

The present invention covers a loom having means for introducing the filling threads by fluid with the means for introducing the filling threads having a comb of parallel channel forming blades to form a guide channel for the fluid, the channel forming blades arranged on the side of the reed facing the fell of the cloth.

The present invention relates to devices for use in a loom for fluid insertion of the filling yarn, the loom having a reed, each of whose teeth defines a bulge with the opening of the bulge facing the fell of the cloth being woven to provide for better beat-up, all of said bulges together forming a guide channel for the passage of fluid which serves for the insertion of the filling yarn.
