Circular spreader with a locking mechanism for keeping the spreader in a spread condition

摘要

Circular spreaders for tubular textile goods make it necessary to keep the spreader arms in a desired spread-out condition so that an unintended reduction in the diameter of the circular spreader is prevented. Such unintended reduction could be caused by operational vibrations or by impacts to which the spreader may be exposed during operation. For this purpose the spreader is equipped with a locking mechanism which, on the one hand, permits a continuous adjustment or a stepwise adjustment of the circular spreader to a maximum spread diameter and which, on the other hand, prevents a reduction of the once adjusted spreader diameter. A ratchet mechanism is provided for this purpose.
