Definitions

  • the present invention relates to an air-type tuck-in operation in a fabric-cloth moving type pile loom and in a beating-up position changing type pile loom.
  • a relative distance between a cloth-fell position of a fabric cloth and a beating-up position for a loose-pick and that for a fast-pick are made different from each other.
  • the cloth-fell position and the beating-up position substantially coincide with each other.

  • the pile loom is what is called a fabric-cloth moving type pile loom.
  • a servo motor is provided as a dedicated actuator that drives a fabric-cloth moving device, which is a terry motion device.
  • the servo motor is controlled by a controlling device that is different from a controlling device of a loom motor.
  • a beating-up position changing type pile loom is also available as a pile loom.

Consequently, after the loose-pick, that is, after the beating-up for the loose-pick, it becomes difficult to insert the weft ends into the weft shed, as a result of which the weft ends are erroneously tucked in, thereby impairing the quality of the pile fabric.
  • EP-A-1 130 145 is known an air-type tuck-in device, which is also used in a pile loom, including a terry motion member, having a setting device in which tuck-in modes are recorded which include as information particular picks at which tuck-in operations are to be performed.

  • a pick at which a weft end is tucked into a fabric cloth as a result of jetting air from a nozzle, is set for each terry mode as a tuck-in mode.
  • a terry mode during the operation of the loom is changed, it is possible to change to a tuck-in mode that is suitable for the terry mode. Therefore, in the pile loom, even if a terry mode is changed during the operation of the loom, tuck-in operations at picks suitable for the respective terry modes are executed. Consequently, erroneous tuck-in operations are reduced, and tuck-in selvages having good appearances are formed, so that a high-quality pile fabric can be obtained.
  • terry modes and tuck-in modes corresponding to the terry modes are both controlled in a programmable manner. In addition, different terry modes are repeated. Therefore, a pile fabric having a predetermined texture and a tuck-in selvage having a good appearance are obtained.
  • tuck-in modes that are different from other tuck-in modes are set for particular terry modes.

  • the reed 6 does not reach the cloth fell Cc of the fabric cloth C, so that what is called a "partial beating-up" operation is performed.
  • a warp shed spreads towards the reed while being restricted by a weft Ya for the beaten-up loose-pick.
  • the warp shed serving as a space for inserting a weft end Ya, spreads towards the reed from the cloth fell Cc
  • the warp shed serving as the space for inserting a weft end Ya, spreads towards a let-off side from an intersection of an upper warp and a lower warp, which is provided as a result of restricting the warp shed by the weft end Ya for the loose-pick.
  • the warp shed is moved closer to the let-off side than after the "complete beating-up" operation is performed, thereby making it difficult to perform a tuck-in operation by the tuck-in nozzles 1a.
  • the tuck-in modes are recorded in a setting device 14 so that tuck-in modes for executing tuck-in operations for undesirable picks in one unit of pile formation cycle are removed. Therefore, it is possible to prevent erroneous tuck-in operations.
  • Fig. 8 is a table showing tuck-in modes for respective terry modes recorded in the setting device 14. As in the second embodiment, a plurality of different tuck-in modes are recorded depending upon the terry mode type.
  • Fig. 9 is a table showing control data set in the setting device 14. A plurality of different tuck-in modes are recorded depending upon the terry mode type. Therefore, an operation for setting the tuck-in modes for the respective terry modes as control data is required.
  • different tuck-in modes are set. More specifically, in the example shown in Fig. 9 , terry modes 2L2F and terry modes 2L3F are set as particular terry modes that are executed at different time periods and that are of the same terry mode type.
  • terry modes 2L2F different periods of Steps 1 to 8 and Steps 19 to 22, that is, different steps are set.
  • different tuck-in modes a No. 2 tuck-in mode and a No. 3 tuck-in mode in the table shown in Fig. 8 .
  • the tuck-in mode that is suitable for the weaving condition is set as the control data.
  • different tuck-in modes a No. 6 tuck-in mode and a No. 5 tuck-in mode in the table shown in Fig. 8 , are set.
  • the terry modes 2L2F are set.
  • tuck-in operations are set for the No. 2 tuck-in modes (shown in Fig. 8 ), that is, a first loose-pick and second fast-picks.
  • terry modes 2L3F are set.
  • tuck-in operations are set for the No. 6 tuck-in modes (shown in Fig. 8 ), that is, first loose-picks and second fast-picks.
  • a terry mode 2L2F is set.
  • tuck-in operations are set for the No. 3 tuck-in mode (shown in Fig.
  • a terry mode 2L3F is set.
  • tuck-in operations are set for the No. 5 tuck-in mode (shown in Fig.
  • Steps 1 to 27 constitute one unit of weaving cycle.
  • the number of repetition of one unit of weaving cycle is set, so that a loose-pick or a fast-pick in each step, execution or non-execution of a tuck-in operation, and operation or non-operation of a cutter 2 at a side opposite to a weft-supply side are automatically set.
