Method of making card clothing with a reinforcing back |
摘要 |
An arcuate card-clothed element is manufactured by combining a deformable sustaining element which may for example be a slotted stiffener or a layer of fibre glass with a flexible toothed foundation while the sustaining element is in a deformable condition and shaped to the desired arcuate contour of the card-clothed element, and introducing a hardenable bonding medium such as a resin to hold the foundation in the shape of the sustaining element and convert the sustaining element to a substantially rigid state. The card-clothed element may be made in individual sectors, or may comprise sectors cut from a cylindrical assembly built on a former.
