Abstract
The double roller elements for Jacquard machines are produced as one piece plastic carcasses each comprising a central body (60) with end plates (64, 66) integrally hinged thereto. The body has hollow spindles (88) to receive the rollers, (94) and once the rollers (94) have been placed on the hollow spindles, the plates (64, 66) are hinged to cover the rollers (94) and plugs (90) snap into the spindles (88). The cords can be snapped past the gaps between the outer peripheries of the plates (64, 66) to couple the cords to or uncouple them from the element, without unplugging the plates (64, 66) from the spindles (88).

A roller element for a Jacquard machine, said roller element comprising:
- a) an elongated plastics material body comprising a middle region between two end portions;
- b) two cord receiving rollers;
- c) two cover plates;
- d) means for connecting the cover plates to respective ends of the body;
- e) means for receiving the respective rollers and defining spindles therefor:
- said means for receiving being disposed in the middle region of the body and between the rollers;
- and
- f) gaps between the plates and body enabling cords on the rollers to be looped over the plates for the disconnection of the roller element from the Jacquard machine.
A roller element carcass for a roller element for a Jacquard machine, comprising an elongated body of plastics material, two cover plates respectively integrally hinged to the ends of said body, means on the body and-cover plates enabling the cover plates to be hinged onto and snap fitted to the body, said means also defining spindles for the receipt of cord receiving rollers.
A roller element for a Jacquard machine, said roller element having two cord receiving rollers, and wherein the respective cord receiving rollers are trapped between a plastics material body and cover plate means which cover plate means serves to retain cords on the rollers, characterized in that the cover plate means comprises two cover plates, which are integrally connected to the body via integral hinges whereby the body and the plates form a one piece carcass, and the assembly of the element is effected by placement of the rollers followed by the holding of the plates into position trapping said rollers.
