  • Output lever with cam follower rollers for a cam shed-forming mechanism and its manufacturing method, shedding machine equipped with such a lever and loom equipped
    Patent number: 11692286
    Abstract: Output lever (11) with cam follower rollers, where the lever has two follower rollers (24A, 24B) connected to a body (110). The body defines a median plane (P11) which has a central portion (116), with two opposing surfaces (117A, 117B), and two attachment portions (122A, 122B), each connected, by means of a respective attachment device (28), to a respective follower roller. Each attachment device has an inner fastener (28A) and an outer fastener (28B), each of which has one or more flanges (30, 32, 34; 30, 32, 34, 70). The flanges are each formed in a plate and bear bears in parallel planes against each other. Each follower roller is clevis-mounted between the inner and outer fastener so that contact surfaces (S242) of the two follower rollers are located on either side of the median plane.
