Abstract
A process and apparatus for accurately positioning and fixing a loom beam provided with side flanges for winding threads or fabric webs includes a pair of proximity switches which after the loom beam is brought into a prealigned position are positioned between the side flanges to determine the position of the loom beam and if necessary cause an adjustment thereof. The proximity switches are exactly symmetrically aligned with respect to a reference line that is the central line of a pressing cylinder which is provided to smooth the wound fabric webs or threads and extends between the side flanges. In case the proximity switches have different distances to the facing side flanges, the loom beam is realigned until the difference between the distances is compensated.
Claims9
An apparatus for accurately positioning and fixing a loom beam with respect to a pressing cylinder for winding and smoothing fabric webs or a plurality of threads, the loom beam having two spaced and parallel side flanges, said apparatus comprising:
- sensing means for determining the position of the loom beam with respect to the center line of the pressing cylinder by measuring the distance of said sensing means to the side flanges;
- and
- control means for adjusting the position of the loom beam with respect to the center line of the pressing cylinder in dependence on the measurement provided by said sensing means, said sensing means including a pair of proximity switches symmetrically aligned with respect to the center line of the pressing cylinder and movable between the side flanges, said proximity switches measuring the potential between each of said proximity switches and the respectively facing side flanges to determine the distance of the proximity switches from the side flanges.
