Abstract
In a double-gripper weaving machine, intended for weaving plain velvet and carpets, a pile feeder and a combined pile warp beam let-off motion are equipped with a computer in order to calculate the necessary pile warp feed of each operating cycle of the weaving machine and use said calculation as a reference value, both functions pile feeder and pile warp beam let-off motion, being performed directly. The pile warp beam let-off motion has a regulating system consisting of a multi-axis control system provided for one or more pile warp beams.

A pile feeder control system and pile warp let-off motion for a face-to-face weaving machine, for weaving plain velvet and carpets, comprising a pile feeder and a pile warp beam let-off motion equipped with a computer suitable for calculating the necessary pile warp feed rate for each operating cycle of the weaving machine and using said calculation as a reference value, wherein a computer-controlled or a direct pile beam drive directly controls operation of both the pile feeder and pile warp beam let-off motion together, and wherein the pile warp beam let-off motion comprises a regulating system consisting of a multi-axis control system provided for one or more pile warp beams.
A system for the control of a pile feeder and of the pile warp let-off motion from a pile warp beam in a face-to-face weaving machine, said beam being driven by a motor, said system comprising:
- (a) a computer system calculating the necessary pile warp feed rate for each operating cycle of the weaving machine;
- (b) a measuring system for measuring the current diameter of the pile warp beam, said system being adapted to send a signal to said computer system;
- (c) a regulator for said motor, said regulator being adapted to receive a feedback of said motor and to send a signal to the computer system whereby the computer system comprises:
- (a) a low-speed regulating circuit associated with the regulator for controlling the motor speed as a function of the diameter of the pile beam measured by the measuring system, and
- (b) a high speed regulating circuit associated with the regulator for controlling the motor as a function of a desired pile feed rate and as a function of the weaving speed of the machine.
A face-to-face weaving machine comprising a pile feeder control system and a pile warp let-off motion, wherein a pile feeder and a pile warp beam let-off motion are equipped with a computer for calculating the necessary pile warp feed rate for each operating cycle of the weaving machine and for using said calculation as a reference value, wherein a computer-controlled direct pile beam drive directly controls operation of both the pile feeder and pile warp beam let-off motion together, and wherein the pile warp beam let-off motion comprises a regulating system consisting of a multi-axis control system provided for one or more pile warp beams.
