Description
Card flat for a carding machine, which card flat has a carrying member, which has a clothing-holding part and a rear part The invention relates to a card flat for a carding machine.
It is known for a card flat to have a carrying member, which has a clothing-holding part and a rear part, there being associated with the carrying member two end head parts which slide on a slideway and cc-operate with an endless flexible driving element, for example a drive belt, there being provided a drive transfer element which is in engagement with the end head parts and the drive belt, wherein an end region of the drive transfer element is fastened in a recess of the end face of the carrying member.
In the case of a known card flat (EP 0 794 272 A), coupling between the flat and a toothed belt is achieved by means of a cylindrical form fit, without fixed retention means. The toothed belts are positioned at their ends by means of cavities provided in the toothed belt and by means of one pin of circular cross-section, the axis of which extends transversely to the toothed belt at each end of the flat. At each end of the flat there is fixed a horizontal pin of circular cross-section for insertion into the cylindrical cavity. The pin is of cylindrical shape and has a size coherent with the cavity, in order to enable the flat to be driven along its working path. The pins are fixed in the carrying member of the flat, for example, by means of a forced fit (force-based connection) or by a screwed connection.
At the two ends of the carrying member of the flats there are provided, in a position arranged close to the bottom face, two supporting pins made of wear-resistant material, for example alloy steel, which are horizontally positioned and intended for sliding on the slideways, in order to support the flats located opposite the cylinder.
The horizontal pin for insertion into the cylindrical cavity of the toothed belt is fastened in a position which is located relatively further away from the lower bottom face of the carrying member.
A disadvantage of the known card flat lies in the fact that connection of the components is made by pressing in the pin (press fit) . In the process, the pin and the recess can undergo plastic deformation. Because of the plastic deformation, the drive transfer pin cannot be re-used after removal. In addition, it is disadvantageous that in practice a press fit is hard to release. Finally, the geometry of the carrying member is impaired as a result of the pin.
It is an aim of the invention to provide a card flac of the kind described at the beginning that avoids or mitigates the mentioned disadvantages, wherein especially the connection between the card flat and drive transfer element can be released by simple means and the drive transfer element can be re-used, and wherein there is no impairment of the geometry of the carrying member.
