Abstract
To operate the terry loom, one or more pile-forming elements is actuated by separate drives on an individual pick basis and in a freely triggerable manner and at a loom speed. Any desired terry cadence can be produced in any desired sequence without stopping the loom and changing mechanical control and actuating means. Pile height can also be varied as required. The terry loom has at least one servomotor as a separate drive. The servomotor, which is triggered by means of a control and adjustment circuit arrangement, drives the pile-forming element by way of a reduction transmission and transmission elements. The servomotor can be preferably brushless and electronically commutated and have a low mass inertia rotor and high-field strength permanent magnets.
