Abstract: The needle of an individual embroidery location of a multitude or row of linearly arranged embroidery locations in an embroidery machine is mounted at an axially displaceably guided needle carrier. According to a programmed control and by means of a related switching lever the needle can be individually coupled to or decoupled from an oscillating drive rail which is common to all the needles of the row. A thread guiding roller which is journaled for free rotation at a roller supporting lever and associated with a related one of the needles supplies a thread to the related needle. Simultaneously with the coupling or decoupling of the needle to the oscillating drive rail the roller supporting lever is pivoted between an operative position and an inoperative position in which the thread guiding roller is respectively coupled to or decoupled from a braking member which is common to all embroidery locations.

Abstract: In the rapier or gripper weaving machine a rapier or gripper rod is moved to-and-fro by a drive gear or wheel. An oil lubricating device is provided whose spray nozzle opens in the vicinity of the drive gear or wheel. This spray nozzle is connected to a pressure conduit located at the exit or outlet side of a mixing chamber. In the mixing chamber, a predeterminable quantity of oil taken from an oil reservoir can be admixed with a continuously transmitted flow of compressed air. A timer serves for the periodic activation of an oil dosing and injecting device located upstream or forwardly of the mixing chamber. The dosing action controlled by the timer periodically mixes a predetermined volume of oil into the continuous flow of compressed air being supplied to the spray nozzle. The spray nozzle is a molecular atomizing nozzle.

Abstract: The two-phase gripper loom or weaving machine comprises two loom units arranged adjacent one another. Each of their heald frames can be actuated by a heald frame positioning device with a phase shift of 180 angular degrees. Each heald frame positioning device is associated with a related one of the loom units. There is arranged between the common main shaft of the machine and the two rotary shafts of the two heald frame positioning devices a clutch drive for selectively individually connecting or coupling one or the other rotary shaft with the main shaft of the machine or with an auxiliary drive. This enables, during standstill of the machine, to bring the open weaving shed of one or the other loom unit into a closed shed position until the gripper loom is restarted, prior to which restarting the closed weaving shed is brought back again into the open shed position.

Abstract: A weft thread-selection apparatus for a weaving machine or loom comprises a carrier or support element which oscillates or pivots in cycle with the weft thread-insertion frequency. The oscillatable support element carries at its free end a number of electromagnetic devices, for instance electromagnets corresponding to the number of thread infeed rods and is rotatably supported at its other end for pivotal movement about a shaft. This shaft simultaneously constitutes the pivot point for oscillatable or pivotal arm members, each of which is retained under the action of spring means in its preparatory position. Each of the oscillatable or pivotal arm members is hingedly connected at its free end with one of the thread infeed rods and each oscillatable arm member carries a magnet armature intended to cooperate in a coupling fashion with one of the electromagnets. The row of electromagnets extends below the oscillatable or pivotal arm members.

Abstract: A weft thread-storage apparatus for a loom, especially a gripper loom, comprises a storage for the temporary loop-shaped storage of a filling or weft thread to be inserted into the weaving shed. The substantially box-shaped storage is provided at its one end face or side with an opening of substantially slot-shaped configuration. This opening extends over practically the entire width of the storage. Internally of the storage, in the neighborhood of the slot-shaped opening, there is arranged at least one loop divider in the form of a motor-driven roll. The rotational axis of such roll extends perpendicular to the floor or base surface of the storage and its direction of rotation corresponds to the infeed direction of the weft thread. By regulating the peripheral speed at the roll it is possible to store loops of different length.

Abstract: A fabric or cloth templing device for a loom comprises a part provided with a temple containing a porcupine or needle roller or ring. Over the temple there extends a domed cover member in order to place the selvedge or marginal region of a cloth or fabric web into contact with the needled jacket surface or shell of the porcupine roller or ring. Arranged after the temple is a contact roll which coacts with a countersurface, in order to subsequently fixedly retain the fabric which has been spread by the porcupine rollers. By virtue of these measures it is possible to ensure in a most simple manner an effective traction relief with increasing fabric tension.

Abstract: A detachable connection arrangement is disclosed which comprises a lifter element of a harness lever arrangement wherein at the free end of the lifter element a quadratic or square connection block is rotatable upon a pin or journal and is detachably inserted into a substantially C-shaped claw member at the loom harness. Pin members which are resiliently supported in the claw member engage into recesses at counter surfaces of the connection block and thus form a snap closure. These measures provide a connection arrangement which satisfies all of the requirements placed thereon, especially as concerns simple fabrication thereof, easy connection or release and complete force transmission practically free of wear.

Abstract: An apparatus for picking or firing a projectile-like shuttle contains a pair of rolls revolving at a relatively high rotational speed. The rolls of the roll pair can be simultaneously brought into contact with a related shuttle in order to accelerate the same by frictional forces. To that end the rolls are each arranged upon a pivotal arm and operatively connected with a control arrangement. The rolls possess a predetermined elasticity such that their radial springiness or resilient yielding action at least approximately linearly increases as a function of the increasing radial contact pressure upon bringing the rolls into contact with the shuttles. These measures ensure for a practically wear-free, absolutely precise and controllable mode of operation of the apparatus.

Abstract: An electrical warp thread-monitoring apparatus for a loom wherein a multiplicity of warp threads each carry a drop wire which, in the presence of thread rupture, connects a pair of current rails which are mutually electrically insulated from one another, and thus, closes an alternating-current circuit. The alternating-current circuit possesses at its input side an alternating-current voltage source which can be connected by means of a bridge rectifier with the current rails. This bridge rectifier or rectifier circuit forms the input of a voltage-dependent pulse converter following which there is connected in circuit a RC-integration stage and a threshold value-switching stage, which also then produce a shutdown or stop signal when the contact locations are contaminated and prevent generation of a shutdown or stop signal when contaminants, leakage currents and dancing drop wires produce short pulses.

Abstract: A weft or filling thread monitor comprises a wire-shaped feeler pin which is pivoted by a thread, against the action of spring force, in the region of a measuring field. The measuring field encompasses a light-emitting diode and a photocell and enables generating, in a contactless manner by the feeler pin, an electrical control signal which is related to the monitored thread. This control signal is infed to a first input of a gate switching stage, at the second input of which there is applied a machine-controlled reference signal. In the absence of the control signal there appears at the output a work signal suitable for shutdown of the machine. Due to these measures such thread monitoring apparatus, working with contactless signal triggering, can fulfil all of the requirements placed thereon.

Abstract: A transfer device comprises a transfer lever arranged to execute an oscillatory movement and carries a thread clamp at its free end. This thread clamp comprises a leaf spring constituting a movable, controllable clamping element. The leaf spring can be raised by an actuating lever pivotally mounted on the transfer lever and which is movable relative thereto. At least one thread pick-up or entrainment element and preferably two thread pick-ups or entrainment elements, are arranged on the batten of the loom to position the weft or filling thread in the thread clamp in a predetermined position. This arrangement constitutes a relatively very simple, operationally reliable and self-cleaning transfer device.

Abstract: An apertured disk which is mounted on a shaft in a loom causes a first photocell to transmit a first signal once during each revolution of the shaft in a preselected angular position of the shaft, and a second photocell to transmit a second signal in response to each incremental angular displacement of the shaft through one degree. A counter is reset to zero in response to reception of each first signal, and the counter thereupon counts the second signals until the shuttle of the loom causes the generation of a third signal which is generated when the shuttle reaches a predetermined portion of its path. The counter displays or otherwise indicates the number of second signals which are generated between the generation of a first signal and the generation of the next following third signal.
