Title:
CONTROL LEVERAGE MECHANISM FOR TUCK-IN DEVICE WITH TRAVELLING OPERATING HEAD FOR LOOM
Document Type and Number:
Japanese Patent JP2016183442
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a travelling-head tuck-in device provided with a new-concept control which does not require the use of cylindrical guides to obtain the alternate translation movement of a travelling head.SOLUTION: In a control leverage mechanism of a travelling-head tuck-in device for a loom, functional groups of levers include: a first articulated quadrilateral, the hinge ends (1, A) of which are fixed to a loom, and which takes alternate movement from a loom sley S; a connecting rod-crank mechanism which receives, on a crank L2, movement from the first articulated quadrilateral and transmits it through a connecting rod LR to a travelling head LC of the tuck-in device in B connected by a hinge; and an articulated parallelogram which connects the body of the tuck-in device to the travelling head LC, for guiding the travelling head LC of the tuck-in device between a forward home position and a backward operating position, along an arc wide enough to approximate a rectilinear movement.SELECTED DRAWING: Figure 1
