Warp knitting machine with thread sheet turning arrangement

Abstract

A flexible sheet turning arrangement located in a thread path upstream of the guides in a warp knitting machine that has a machine frame and at least one plurality of guides. The arrangement has a set of springs with proximal ends supported on the machine frame, and free distal ends. Also included is a turning element running the full width of the machine and attached to the free distal ends of the set of springs. The set of springs may include a package having at least two leaf springs placed on top of each other and joined at their ends. At least one of the springs may be made of a material having a greater internal coefficient of friction than steel. The springs may be laid to provide such a level of damping that the damping coefficient δ satisfies a relationship involving Td the period of oscillation, and ;i, ;i+1 the neighboring amplitudes of damped oscillations.
