Abstract
A loom having a first drive motor (10), which for instance drives a batten (13), and having at least one second drive motor (44), which drives a dobby (46), is provided with a control and regulating device (48), which forms a rotational angle course for a virtual synchronization shaft of the loom and communicates such rotational angle course to respective control and regulating units (49, 51) of each of the drive motors (10, 44), which synchronize the drive motors in at least one angular position relative to the virtual synchronization shaft.
Claims19
A method for operating a loom having a first drive motor which drives a first loom element and at least a second drive motor which drives a second loom element, said motors each having a control and regulation unit associated therewith, comprising forming a rotational angle course for a virtual synchronization shaft of the loom;
- and synchronizing the elements driven by the drive motors so that the elements are synchronized with the virtual synchronization shaft at one or more predefined angular positions only, and are driven by the drive motors independently of each other irrespective of synchronization with each other and the virtual synchronization shaft at positions other than said one or more predetermined angular positions by operating the drive motors independently of each other at the other positions.
A loom having a first drive motor which drives a first loom element and at least a second drive motor which drives a second loom element, comprising a control and regulating device which is arranged to form a rotational angle course for a virtual synchronization shaft of the loom and to communicate signals related to such rotational angle course to respective control and regulating units of each of the drive motors, which are arranged to synchronize each of the elements driven by the drive motors in at least one predetermined rotational angle position with the virtual synchronization shaft on the basis of such signals in a manner such that the elements are synchronized with the virtual synchronization shaft at said at least one predetermined rotational angle position, and to drive the respective drive motors independently of each other irrespective of synchronization with each other and the virtual synchronization shaft at positions other than said at least one predetermined rotational angle position.
