摘要

To accelerate the working of a loom, the shuttles are moved through the shed using a linear motor principle. To accelerate the weaving action, at a loom, the shuttles are not beaten to propel them through the shed but linear magnets with a control system are located along and within the shed without contact. The attraction magnets of the linear motor give an acceleration or braking action. The loom width can be selected as required, with a suitable geometric array of warps. The warps and the linear motor are in a circle e.g. for a circular loom, which is open at set points to insert a shuttle after a bobbin change. The wefts are carried through the shed by the shuttles and, in addition to the forward movement, are given a pressure of beating movements as hammer blows against the woven fabric. The shuttles can be in a variety of dimensions and weights, to take larger bobbins and reduce the number of bobbin changes. The movements of the shuttles, together with their acceleration and braking, are controlled by the linear motor.
