Abstract

Abstract IN A MACHINE FOR CONTINUOUSLY PACKAGING TUBULAR RIVETS IN END-TO-END CONFIGURATION, A SUCCESSION OF RIVETS IS FED DOWN A TUBE, WITH THE ASSISTANCE OF A STREAM OF COMPRESSED AIR, TO A PACKAGING STATION PROVIDED BY THE NIP OF TWO PACKAGING ROLLERS EACH HAVING A RESILIENT RUBBER SURFACE. TWO PACKAGING ROLLERS EACH HAVING A RESILIENT PACKAGING ROLLERS, ONE TAPE ON EACH SIDE OF THE SUCCESSION OF RIVETS, TO ENCLOSE THE RIVETS. AT LEAST ONE OF THE TAPES HAS AN ADHESIVE SURFACE WHICH IS PRESSED INTO CONTACT WITH THE OTHER TAPE BY THE PACKAGING ROLLERS. A NARROW MASKING TAPE MAY BE INCLUDED TO PROTECT THE COLUMN OF RIVETS FROM CONTAMINATION BY THE ADHESIVE, IF REQUIRED. ONE OF THE PACKAGING ROLLERS IS PROVIDED WITH A PERFORATOR BLADE TO PERFORATE THE PACKAGE INTO LENGTHS EACH EQUAL TO THE CIRCMFERENCE OF THE ROLER. THE PEFORATED PACKAGE EMERGING FROM THE PACKAGING ROLLERS PASSES THROUGH THE NIP OF A PAIR OF STRIPPER ROLLERS, WHICH ROTATE AT A HIGHER PERIPHERAL SPEED THAN THE PACKAGING ROLLERS AND ARE SPACED FROM THE PACKAGING ROLLERS BY A DISTANCE GREATER THAN ONE LENGTH OF PERFORATED PACKAGE BUT LESS THAN TWO LENGTHS OF PERFORATED PACKAGE. THE STRIPPER ROLLERS SEPARATE EACH LENGTH OF PACKAGE AWAY FROM THE FOLLOWING ONE AT THE PERFORATIONS BETWEEN THEM. THE RIVET FEED TUBE IS PROVIDED WITH RIVET SENSING DEVICES WHICH ARE CONNECTED TO CONTROL THE DRIVE TO THE PACKAAGING ROLLERS, SO THAT THE PACKAGING ROLLERS OPERATE ONLY WHEN THERE IS A COLUMN OF RIVETS IN THE FEED TUBE SUFFICIENT TO FILL AT LEAST ONE LENGTH OF PACKAGE.
