摘要

#CMT# #/CMT# The longitudinal cutting device has a corrugator that is comprised of longitudinal grinding knives and grinding facilities that are equipped with grinding discs. An abrasive material (2) and an abrasive carrier (1) are positively connected. The abrasive material and the abrasive element are connected axially and non-rotatably. The abrasive material and the abrasive carrier are positively connected with a supporting device. #CMT# : #/CMT# An independent claim is included for a method for manufacturing grinding wheel for grinding knife for longitudinal cutting device. #CMT#USE : #/CMT# Longitudinal cutting device used for cutting corrugated cardboard sheet. #CMT#ADVANTAGE : #/CMT# The undesired detachment of the abrasive material from the abrasive carrier during the operation of the longitudinal cutting device can be prevented reliably. The damage of the cutting device due to falling of the fragments of the corrugated cardboard sheet can be prevented reliably. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the sectional views of the longitudinal cutting device. 1 : Abrasive carrier 2 : Abrasive material 3 : Screw thread.
