Claim 1
Independent Claim
142 words
THE METHOD OF TREATING SUBSTANTIALLY DRY TUBULAR KNITTED FABRIC TO PROVIDE FINISHED, PRE-SHRUNK MATERIAL SUITABLE FOR MANUFACTURE INTO GARMENTS WHICH COMPRISES, RECEIVING THE FABRIC IN A SUBSTANTIALLY DRY STATE, SETTING THE FABRIC TO PREDETERMINED WIDTH BY SPREADING THE FABRIC TO SUBSTANTIALLY FLATTENED FORM, STEAMING THE SPREAD FABRIC, DISCONTINUING THE SPREADING STEP AND BRINGING THE SPREAD AND STEAMED MATERIAL INTO EDGE TO EDGE CONTACT WITH A SURFACE MOVING AT A PREDETERMINED FIRST SPEED WHILE MAINTAINING SUBSTANTIAL CONTROL OVER THE DIMENSIONS OF THE FABRIC, AND FORCIBLY COMPRESSIVELY SHRINKING THE SPREAD AND STEAMED FABRIC LENGTHWISE BY FEEDING THE FABRIC ACROSS ITS WIDTH ON SAID SURFACE AND AT SAID PREDETERMINED FIRST SPEED INTO A PREDETERMINED COMPRESSING ZONE, DECELERATING THE FABRIC ACROSS ITS WIDTH IN SAID ZONE, AND SUBJECTING THE COMPRESSED FABRIC TO LOCALIZED PRESSURE IN THE PRESENCE OF HEAT AT THE TERMINAL END OF SAID ZONE.

Claim 3
Dependent Claim
153 words
APPARATUS FOR FINISHING SUBSTANTIALLY DRY TRAVELLING TUBULAR KNITTED FABRIC COMPRISING MEANS FOR FLATTENING AND SPREADING THE FABRIC AND SETTING IT TO PREDETERMINED WIDTH, MEANS FOR STEAMING THE FABRIC DURING ITS PASSAGE ALONG SAID FLATTENING AND SPREADING MEANS, AND FABRIC TREATING MEANS POSITIONED TO RECEIVE FABRIC SUBSTANTIALLY DIRECTLY FROM THE FLATTENING AND SPREADING MEANS AND WHILE MAINTAINING SUBSTANTIAL CONTROL OVER THE DIMENSIONS OF THE FABRIC, SAID TREATING MEANS BEING ADAPTED TO FORCIBLY COMPRESSIVELY SHRINK SAID FABRIC LENGTHWISE AND COMPRISING A PAIR OF NIP ROLLERS FORMING A PORTION OF A COMPRESSION ZONE, ONE OF SAID NIP ROLLERS BEING POSITIONED TO RECEIVE FABRIC SUBSTANTIALLY DIRECTLY FROM SAID FLATTENING AND SPREADING MEANS AND BEING DRIVEN TO PROPEL SAID FABRIC ACROSS ITS WIDTH AT A PREDETERMINED SPEED, THE OTHER OF SAID NIP ROLLERS BEING POSITIONED DIRECTLY ADJACENT THE FIRST, TO FORM A NIP, AND BEING DRIVEN TO DECELERATE THE FABRIC ACROSS ITS WIDTH TO A PREDETERMINED DECELERATED SPEED.
