tape for transporting clamps portatrama through the step of looms weaving and process for the production thereof

摘要

in a tape for the transport of pliers portatrama in step frames of weaving, the flexible having holes aligned along the same axis, four cornered.to undertake the teeth of the gear wheel to drive, these holes have longitudinal section boat with profiles of the transverse faces of hole inclined convergent.the tape is produced by a process which includes the steps of: (a) to the tape holes of small size for four cornered cutting; (b) provide by brocciatura a ofthe transverse faces of these holes a profile inclined convergent than the other side; and (c) set by the other side of the hole brocciatura transverse profile angleconvergent than the first face.
