FIELD: equipment for winding spirals, possibly spirals for spring mats, soft furniture.
SUBSTANCE: apparatus includes cylindrical mandrel mounted by cantilever fashion; mechanism for adjusting pitch arranged after mandrel; cylindrical sleeve for orienting wound spiral. Said sleeve is arranged coaxially relative to mandrel directly near its outlet and it has inner diameter equal to outer diameter of spiral. Sleeve is mounted with possibility of rotating around axis of mandrel having groove. Said groove is arranged on cylindrical surface of mandrel along helical line with minimally set pitch of spiral. Mechanism for adjusting pitch is in the form of pin rigidly mounted in orienting sleeve across its axis.
EFFECT: simplified design, assembling and adjustment, enhanced operational reliability of apparatus.
