摘要:
A start restriction method of a pile loom (1) from which an operator removes a defective yarn when a weft-insertion failure occurs includes previously storing a start reverse-rotation number set so that a same numerical value as a pile step is assigned to a loose pick and a first fast pick included in pile picks, and 1 is assigned to second and later fast picks; when a weft-insertion failure occurs, reading from the start reverse-rotation number and storing as a current value, a numerical value corresponding to the pile pick with the failure; updating the current value by adding 1 (subtracting 1) every time when a rotational angle of a main shaft (24) passes 0° by forward (reverse) rotation of the main shaft through a subsequent motion of the loom; and inhibiting start of the loom by an operation on an operation button (26) until the current value becomes 0.
摘要:
There is provided a method for controlling shed opening of pile warp yarns in a pile fabric loom. The pile fabric loom includes a plurality of heald frames through which the pile warp yarns are passed, and a plurality of drive devices driving the respective heald frames and forms piles by forward and rearward movement of cloth fell. The method is characterized by setting a shed opening amount of the pile warp yarns at a start of weft insertion in fast picking larger than a shed opening amount of the pile warp yarns at a start of weft insertion in loose picking.

A pile orientation device for pile fabric loom includes a cloth guide member and a pile orientation member. The pile fabric loom for producing a woven cloth has a terry motion. The woven cloth is moved reciprocally in the front-and-rear direction of the pile fabric loom to shift a cloth fell position by the terry motion and piles are formed in the woven cloth by the terry motion. The cloth guide member is movable reciprocally in the front-and-rear direction of the pile fabric loom by the terry motion and guides the woven cloth toward the winding side of the pile fabric loom. The pile orientation member is used for pressing the woven cloth on the cloth guide member. The pile orientation member is mounted on the pile fabric loom without being moved in the front-and-rear direction of the pile fabric loom by the terry motion.

A driving device for let-off-side and take-up-side terry motion members (15, 16) included in a cloth-shifting-type pile loom (1) includes drive-transmission mechanisms (20, 30) provided respectively for the two terry motion members (15, 16) and both linked to a driving shaft (mls) of common driving means (ml) provided for the two terry motion members (15, 16). The drive-transmission mechanisms (20, 30) include a rocking member (18) rocked by the driving means (ml), supporting units (24, 34) respectively supporting the terry motion members (15, 16), and linking means including at least one linking member (22, 26, 27, 28, 29, 32) that links the rocking member (18) to the supporting units (24, 34). One of the drive-transmission mechanisms (20, 30) corresponding to the let-off-side or take-up-side terry motion member (15, 16) is additionally provided with drive-changing means (40, 50, 60, 70) having a designated actuator (m2) as a driving source and changing a rocking position of one of the supporting units (24, 34) included in the drive-transmission mechanism (20, 30) with respect to a certain rotary phase of the driving shaft (m1s). The drive-changing means (40, 50, 60, 70) is actuated in a shifting process of the terry motion member (15, 16).
摘要:
In the case of a terry loom with a drive (26) for moving backrest (14) and breast beam (23) to and fro, provision is made for the drive (26) to comprise its own drive motor (31), which drives a shaft (33) which is connected to the holding elements (28, 30) of backrest (14) and breast beam (23) by means of transmission elements (37, 38).
摘要:
In a cloth-shifting-type pile loom (1), one of drive-transmission mechanisms (20, 30) that links a supporting unit supporting a let-off-side or take-up-side terry motion member (15, 16) with a driving shaft includes at least two linking members, which may include a first linking member (22, 32, 44) and a second linking member (26, 36). The first linking member (22, 32, 44) is rotatably supported by a supporting shaft fixed in position, and the second linking member (26, 36) is connected to an end of the first linking member (22, 32, 44) proximate the supporting unit (24, 34). The first linking member (22, 32, 44) and the second linking member (26, 36) at the time of a fast-pick beating operation are connected in a manner such that a connection part between the first linking member (22, 32, 44) and the second linking member (26, 36) is positioned on or near a line extending between the supporting shaft for the first linking member (22, 32, 44) and an end of the second linking member (26, 36) proximate the supporting unit (24, 34).
