Title:
MICRO-ADJUSTMENT RETURN MECHANISM
Document Type and Number:
WIPO Patent Application WO/2012/105395
Kind Code:
A1
Abstract:
Provided is a tensioner for an overlock machine, which can collectively adjust, with one dial, the thread squeezing pressure of each tension adjustment mechanism, and in which the position of a tension plate does not change despite a micro-adjustment to the thread squeezing pressure. The following are coaxially disposed: a plurality of tension plates (21), each of which has one end side that applies, to each thread, the thread squeezing pressure set depending on the sewing method; a plurality of impelling members (25) impelling the tension plates (21) by the thread squeezing pressure; and a plurality of end face cams (24) having mutually different profiles, and controlling the impelling force of the impelling members (25). Also provided are: an operation dial (3) that collectively rotates the plurality of end face cams (24); and a tension plate pressing gear (26) that can coaxially move leftward and rightward, between the tension plates (21) and the impelling members (25), so as to adjust the impelling force of the impelling members (25).
