The knife consists of a long metal knifeholder, made of aluminium for lightness, with a knifeand guide w^hich are held in position by a trigger motion,fixed in a slot. The guide is slightly bent so as to permitthe operator to hold the knife at a suitable angle tomeet the cloth. The piece of velvet to be cut is made into a continuousweb by sewing the two ends together, and it is thencarried over a series of rollers in order to give the neces-sary tension to the piece on the top where it meets theknife. To give this tension the cloth passes over fourrollers at the front, only one of which is covered, theothers being plain. The tension of the piece is tightright across its full width, and an ingenious arrangementof nipping rollers in the middle of the machine helps tostart the g So^ 60 VELVET AND CORDUROY INDUSTRY The machine is driven from a shaft at the back, whichalso drives the creeping arrangement, carrying the slackof the piece along the base of the machine, while theplaiter lays the piece into folds, and all the other sub-sidiary drives are from the back shaft also. The resultof this is that when it is necessary to stop the machinethe stop movement is instantaneous, as everything isdriven from this rear shaft. Directly the knife and guidestrike any obstruction in the race, the trigger movementis at once released, and the knife and guide are thrownout of action before they can make anything but a verysmall hole. At the same time the operator takes herfoot from the forward pulley, and semi-automaticallytouches the reverse—^thus bringing the brake motioninto action immediately. To pick up the race again,the operator has just
