Embodiment Construction

[0019] Referring now to the drawings, the dobby shown in Figures 1 and 2 comprises a main shaft 1 energized by intermittent rotary motion which stops every half revolution. The shaft 1 houses a series of roller bearings, the number of which is the same as the number of healds or needle bars of the loom. A laterally extending eccentric 2 is mounted loosely on each roller bearing with a disc (plate) 3 . On each eccentric 2 the opening of the connecting rod 4 is installed empty, the free end of the connecting rod 4 is connected with the pivot arm 5, which ensures the The vertical movement of the heddle 6 of the needle bar, the heddle 6 is shown schematically in the figure.

[0020] Between two adjacent eccentrics 2, the splined shaft 1 supports a drive disc 7, which is firmly connected to the shaft 1 and has two diameters cut out diametrically opposite each other on its periphery. to the notch 7a. These notches 7 a are intended to selectively receive the end fingers 8 a of a p...

Abstract

The dobby has, at each blade level thereof, a vibration element associated with an operation element, at least one movable connecting element supported by the operation element and two swing levers receiving, at one side, action of a reader and, at the other side, action of a elastic device. The elastic device connects a catch of the swing lever with a jamming face, set at the operation element, or the connecting element and the lever connected with the jamming face is out of a selector of the reader. And a mechanical element independent from the reader moves, resisting to the action of the elastic device, the lever having the catch unconnected with the jamming face. Thereby, the lever does not interact with angular motion of the selector.

Description

technical field [0001] The present invention relates to a rotary dobby for controlling a heddle mounted on a loom and a loom having the same. Background technique [0002] In a rotary dobby, the reciprocating vertical movement of the heald is ensured by a link / swing link assembly, such an oscillating assembly being controlled by an actuating member in the form of an eccentric. The actuating member is mounted on a main shaft of the dobby excited by intermittent rotary motion and, when the axle is stopped, a reading device (reading device) controls the connection of the actuating member to the axle , to control an oscillating member according to the design (pattern) or weave to be obtained on the fabric being woven. [0003] FR-A-2540524 discloses a rotary dobby in which the selective connection is obtained by means of a disc firmly connected to the eccentric forming the actuating part and comprising two diametrically opposite notches, which The mouth is adapted to cooperate...
