Function & Production

About Leno Device

The leno unit forms a locked selvedge, which is essential on air jet and water jet looms where weft tension at the edge is low.

We supply leno device housings, discs, gears, shafts, springs and mounting brackets, machined to the loom reference.

Wearing elements such as discs and gears are offered in hardened grades to extend the service interval between replacements.
