Claims21
Apparatus for operating and controlling a textile machine designed for processing a roving in order to form it into a yarn made from a continuous sequence of portions, each portion having predetermined count and/or twist characteristics,
- the apparatus comprising;
- at least one driving means connected for operation to an operating shaft, the operating shaft being capable of carrying out processes on the roving designed to produce the yarn;
- at least one operating device, connected for operation to the driving means, the operating means being capable of operating the driving means according to reference signals;
- at least one control device connected for operation to the operating device;
- wherein the control device comprises first means for generating a reference signal for keeping the count and/or twist characteristics constant along the yarn;
- together with second means for generating a reference signal for producing count and/or twist characteristics which are variable along the yarn;
- and
- additionally, means for selecting the operation of the driving means, connected for operation to the control device, and capable of enabling or disabling the first means and the second means.
Method for processing a roving on a textile machine in order to form it into a yarn;
- the yarn consisting of a continuous sequence of portions, each portion having a predetermined length and predetermined count and/or twist characteristics;
- the method comprising the stages of:
- selecting means for generating a reference signal for keeping the said count and/or twist characteristics constant along the yarn or means for generating a reference signal for producing count and/or twist characteristics which are variable along the yarn;
- sending the reference signals to an operating device connected for operation to at least one driving means;
- and
- operating the driving means in accordance with the reference signals for the execution of the process on the yarn.
Method for processing a roving on a textile machine in order to form it into a yarn;
- the yarn consisting of a continuous sequence of portions, each portion having a predetermined length and predetermined count and/or twist characteristics;
- the method comprising the stages of:
- inserting a hardware key into the textile machine and/or connecting it to the machine;
- selecting means for generating a reference signal for keeping the count and/or twist characteristics constant along the yarn or means for generating a reference signal for producing count and/or twist characteristics which are variable along the yarn, in accordance with the hardware key;
- sending the reference signals to an operating device connected for operation to at least one driving means;
- and
- operating the driving means in accordance with the reference signals for the execution of the process on the yarn.
