Fineblanked Stamped Parts for Textile Machinery

Fineblanking is the precision end of stamping: a press process that cuts flat metal parts with fully sheared, square edges and flatness that ordinary stamping cannot reach, so parts come off the press ready to use in precision mechanisms. Textile machinery is full of such parts — knitting elements, latch and blade forms, ratchets, levers and plates — where edge quality decides whether a part slides, latches and survives millions of cycles. Fineblanked and stamped parts for the industry come from specialist groups such as Kern-Liebers, listed below.

Fineblanking and the Textile Machine Parts It Makes

In fineblanking, the blank is held under high pressure on all sides while the punch cuts, so the metal flows rather than tears: the result is a part with a smooth, full-depth sheared edge, tight tolerances and no secondary finishing. That suits the small, hard-working flat parts of knitting and textile machines — elements that must present a perfect edge to yarn or to a mating part millions of times a day. The Kern-Liebers group, whose range anchors this page, has 34 companies worldwide producing springs, fineblanked and stamped parts and knitting elements, with approximately 4,000 employees worldwide — a scale that reflects how many machine builders draw on specialist stampers rather than pressing in-house.

Fineblanked, Stamped and Bent Parts — Choosing the Process

Ordinary stamping and bending serve the less critical parts: brackets, covers, guides and formed components, covered in this directory under stamped bent parts. Fineblanking is specified where edge quality, flatness and tolerance are functional — where a torn stamping edge would snag yarn, wear a mating surface, or vary from part to part enough to upset a mechanism. For spares, identification is by the machine maker's part number and drawing; fineblanked parts are not improvised substitutes, because their edge condition is part of the design. The same group's springs and loop forming elements appear on their own pages in this section, and its knitting machinery spare parts range ties the families together.
