Card flat bar for a carding machine, for cotton, synthetic fibers or the like, having a card flat clothing

A card flat bar for use in a carding machine opposite a clothed roller of said machine, having a card flat bar body having a material inlet side at which in use fibre material is received, and a card flat clothing strip which is magnetically attachable to the card flat bar body, wherein the card flat bar body includes a counter-bearing associated with said material inlet side and the card flat clothing strip comprises a counter-element arranged to co-operate, in use, with the counter-bearing in a direction towards said opposed clothed roller, and wherein a foot portion of the card flat bar body is magnetic or includes a magnetic element and the clothing strip comprises one or more magnetic elements for magnetic attachment of the clothing strip to the card flat bar body.

A card flat bar for use in a carding machine opposite a clothed roller of said machine, having a card flat bar body having a material inlet side at which in use fibre material is received, and a card flat clothing strip which is magnetically attachable to the card flat bar body, wherein the card flat bar body includes a counter-bearing associated with said material inlet side and the card flat clothing strip comprises a counter-element arranged to co-operate, in use, with the counter-bearing in a direction towards said opposed clothed roller, and wherein the magnetic force is greater between the clothing strip and the card flat bar body than the forces that, in use, act on the clothing, the arrangement being such that under normal operating conditions the counter-bearing and counter-element are not in contact with one another whilst in abnormal operating conditions the removal of the clothing strip can be prevented by contact between the counter-bearing and counter-element.

A card flat bar for a carding machine for cotton, synthetic fibres and the like, opposite a clothed roller of said machine, having a card flat clothing, wherein the card flat clothing, which is arranged in a strip-shaped support layer, is attached to the card flat bar and at least the regions of the card flat clothing that face the card flat bar consist of an iron material, with at least one magnetic means being provided between the card flat bar and the regions of the card flat clothing that face the card flat bar, wherein on the fibre material inlet side of the card flat clothing—seen in the direction of rotation of the cylinder—there is associated with the card flat bar a counter-bearing, stop or the like with which the base co-operates in the direction towards the cylinder, and wherein there is a spacing between the upper side of the counter-bearing and the underside of the regions of the card flat clothing that face the card flat bar, which spacing is smaller than the spacing between the card flat clothing and the clothed roller.

A flexible clothing for a card flat bar on a carding machine wherein opposite a clothed roller of said machine, wherein the card flat clothing is attachable to the card flat bar and at least the regions of the card flat clothing that are arranged to face the card flat bar consist of an iron material, in which on the fibre material inlet side of the card flat clothing—seen in the direction of rotation of the cylinder—there is a counter element with which a counter-bearing of the base of the card flat bar can co-operate in the direction towards the cylinder, and wherein there is a spacing between the upper side of the counter-bearing and the underside of the counter-element, which spacing is smaller than the spacing between the card flat clothing and the clothed roller.
