Apparatus for the measurement of tensile stresses on bands,filaments or the like
Abstract
Abstract D R A W I N G TESTING APPARATUS FOR MEASUREMENT OF TENSILE STTESSES ON ELONGATED FLEXIBLE BAND-LIKE OR FILAMENTARY PRODUCTS HAS TWO STATIONARY GUIDE ROLLERS AND A MOVABLE TESTING ROLLER WHICH IS DISPLACED THROUGH SHART DISTANCES IN RESPONSE TO CHANGES IN TENSILE STRESSES UPON THE PRODUCT. THE PRODUCT IS TRAINED OVER THE ROLLERS WHEREBY THE TESTING ROLLER CAUSES A TRANSDUCER TO PRODUCE APPROPRIATE SIGNALS WHENEVER THE TESTING ROLLER CHANGES ITS POSITION IN RESPONSE TO A CHANGE IN TENSILE STRESS. THE OPERATING RANGE OF THE TESTING APPARATUS CAN BE BROADENED BY MOVING THE TESTING ROLLER SIDEWAYS INDEPENDENTLY OF THE CHANGES IN TENSILE STRESS TO HEREBY CHANGE THE EXTENT OF OVERLAP BETWEEN THE PRODUCT AND THE PERIPHERIAL SURFACE OF THE TESTING ROLLER.
