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

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.

Interactive loom
10344407 · 2019-07-09 · ·

An interactive loom, which includes a loom-mechanism, a user interface, a loom interface, and a controller. Each cam is in the form of a cylinder rotating about the axis thereof. The circumferential surface of the cam exhibits a determined surface geometry, such that each of a plurality of sections of said circumferential surface corresponds to a respective one of the arms. The circumferential surface further exhibits a respective cross sectional profile and such that each rotational position of said cam is associated with a respective state of lowered and raised arms. The loom-interface includes a motor coupled with the cam, and operates loom-mechanics according to instructions. The controller receives a design from the user-interface and transforms the design into a sequence of states of the arms required for achieving the design. The controller further provides the instructions to the loom-interface. The instructions are associated with state changes of the arms.
