Abstract
At least one of two flexible leaf springs that form a thread gap is controlled by a linearly moveable element of a linear motor or drive. Multi-thread brakes are formed by assembling a plurality of such brakes on a common support whereby a single stator may cooperate with a plurality of linearly moveable armatures forming a corresponding plurality of thread brakes or each thread brake may have its own stator and its own armature arranged in a row either linearly or along a curved support, whereby a compact structure is achieved.
Claims14
A thread brake for weaving looms, said thread brake comprising a support and at least two flexible elements mounted on said support to form a thread gap for passing a thread through said thread gap, a gap width control operatively connected to at least one flexible element of said two flexible elements forming said thread gap, said gap width control comprising a linear motor including a controllable linearly moveable member positioned for operatively influencing said at least one flexible element for adjusting said gap width and a respective brake force.
