An adjustable knot-disalignment device for use in a loom in which weaving is effected by passing a shuttle containing a cop around which a weft yarn is wound between upper and lower warp yarns. The adjusting device includes a disk-shaped reel provided with a circumferential channel for accommodating a wound thread thereon, a thread holding device projecting outward of the circumferential channel of the reel for holding threads and a hooking device for hooking the threads held by the holding device and rotating the threads, thereby winding the threads onto the circumferential channel of the reel. By controlling the number of times the thread is wound around the disc-shaped reel, the knots which connect the threads from two different cops may be made to be disaligned in the woven fabric.

Cop winding device with knot disalignment for shuttle loom

An automatic cop replacing apparatus for a shuttle-type loom with which a cop contained in the shuttle is automatically replaced, including tying the threads together of the old and new cops, and requiring no operator intervention. The apparatus includes a hand for gripping the cop. A rotary arm plate on which the hand is mounted, a drive device for rotating the rotary arm plate and for straightly moving the rotary arm plate in the axial direction, and a drive shaft for moving the rotary arm plate to an exchange position for the cop. A thread tying device holds and ties together the treads of the old and new cops.

Automatic cop exchanging apparatus for shuttle loom

A controlling and supervising system for a loom controlled with a network of computers connected in a network. A host computer provides data files containing dispatching data and production instructions for various units and devices. A data-communication personal computer connected to the network receives data transmitted from the host computer in file and loads the received data into the various units and devices via the network. A plurality of supervisory personal computers are provided for storing the data from the data-communication personal computer and further downloading the data as required, with the addition of operating data, and also supervising predetermined operations and functions of the loom in accordance with signals received from the loom. A controller is installed between the loom and the supervisory personal computer for operating and controlling the loom on the basis of the data from the supervisory personal computer and controlling access to input of signals from the loom and data for use in the operation and control of such equipment and loading the same into the supervisory personal computer.

Controlling and supervising system for loom

A thread-tying apparatus for use in a shuttle loom. The thread tying apparatus includes a grasping claw (122), pressing lever (124), small claw (126), large claw (127), gripping claw (129) and thread tightener (125a). The grasping claws (122) grasp the threads at two locations and rotate the threads so as to form a loop therein which cross at a point. The pressing lever (124) then hooks the crossing point of the threads such that the small claw (126) can grasp the threads at a position offset from the grasping claw (122). Thereafter, the large claw (126) pushes down a portion of the thread such that gripping claw (129) can grab the portion of the thread and pull the thread through the loop which is thereafter tightened by the thread tightener (125a).

Thread tying apparatus for a shuttle loom

An automatic cop replacing apparatus for a shuttle-type loom with which a cop contained in the shuttle is automatically replaced, including tying the threads together of the old and new cops, and requiring no operator intervention. The apparatus includes a hand for gripping the cop, a rotary arm plate on which the hand is mounted, a drive device for rotating the rotary arm plate and for linearly moving the rotary arm plate in the axial direction with respect, thereto and a drive shaft for moving the rotary arm plate to an exchange position for the cop. A thread tying device holds and ties together the threads of the old and new cops.
