Abstract

In a control arrangement for the motor of a winding arrangement, such as a partial warp beam in a warp knitting machine, there is provided a controller. The controller controls the rate of rotation of the motors of the turning arrangements that influence thread consumption and ware takeoff, in dependence on a main shaft signal, a feedback signal and an input size signal. The control arrangement is equipped for the storage of a program containing many input sizes which are addressable sequentially for the control arrangement, in dependence upon the main shaft signal. In particular, a data memory may be provided with a plurality of addresses for the production of differentiable input sizes. An address caller is controlled by the main shaft signal and calls out sequentially the different input sizes for the control arrangement. As a controller, a digital computer is foreseen.

Dependent claims

A control arrangement for a motor of a rotatable winding arrangement having a main shaft, comprising:

(a) a first signal generator coupled to said winding arrangement for generating a main shaft signal signifying the angular displacement of said main shaft;
(b) a second signal generator coupled to said rotatable arrangement for generating a feedback signal bearing a predetermined relation to the extent of rotation of said rotatable arrangement;
(c) input means coupled to said first signal generator and programmed to provide an input size signal that varies in response to said main shaft signal;
and
(d) control means coupled to said input means and said first and second signal generators for controlling the angular speed of said motor of said rotatable arrangement in response to said main shaft signal, said feedback signal and said input size signal, whereby said programmed input means can change the angular speed of said rotatable arrangement.
