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.
