A METHOD AND AN APPARATUS IN A ROTARY STAPLING MACHINE

摘要

The disclosure relates to a method and an apparatus in a rotary stapling machine (10) which, with a stapling module (12) placed in a stapling cylinder (11), applies staples through a plurality of layers in a material web (16) running through the rotary stapling machine (10), at an interval corresponding to a predetermined cutting length (Δ) along the material web (16), the staples being formed by means of a stapling fork (21) in the stapling module (12) in that wire (23) is advanced to a collection position at a forming wheel (22), the wire (23) being cut off whereafter the stapling fork (21) is urged against the forming wheel (22) in order to form the staple which is thereafter collected by the stapling fork (21) and conveyed for application in the material web (16), as well as final forming against a die (15) in a die cylinder (14), wherein the stapling cylinder (11) rotates two revolutions for each cutting length (Δ).
