Loom with a device for controlling the speed of rotation of the main motor of the loom and method for controlling the rotation speed of the main engine of a loom.

摘要

A loom comprising a device for controlling the operating speed of the loom during the starting gear loom-being formed said loom by a first section, essentially including a main motor (M) and a flywheel, and a second section (T), including at least a warping machine and a framing, and which is connected to said first section through a group of main clutch (F) -, such that said first section of the loom, which rotates at a drive speed or predetermined pitch which is higher than the stationary speed of the loom, is connected by means of the group of main clutch (F) to said second section (T) of the loom, in a rest state, characterized in that said main motor (M) is a double-speed motor with two windings (M1 and M2) independently powered by a power supply (A) and apt to develop two rotational speeds stationary (V1, V2), different, predetermined such that a first speed lower (V2) is equal to said stationary loom speed and a second speed, higher, is equal to or higher than said launching speed .
