The cutter '55 2,137,166 cylinder has conventional cutters 46 arranged circumferentially thereof and in‘ shearing rela tion to a stationary cutter 41 which lies in an runs over a roller 20', a lower roller l9’ and a approximately perpendicular plane and spaced front roller l8’ corresponding to the similarly numbered rollers in the ?rst described embodi ment. In the embodiment of the invention shown in Figure 5 the skin to be clipped is laid on the upper ?ight 52 of ,the belt back of the suction ' opening '56 and the belt carries the same along 10 until the opening 56 is reached, whereupon suc below the lower ends of the ?exible ?ngers 35 as illustrated in Figure 4. Suction is present in the housing 43 in a conventional manner to draw the loose ends of the hair'of the skin between the cutters. 10 of the ?ight 53 of the perforated belt 5| is the upper ?ight 22' of the tensioning belt 2|’ which , . 7 The skin is fed over the front upper part of - the revolving. drum l5 so that the belt 28 tensions the same against the upper part of the cylinder I. tion is transmitted from the conduit 55 through and acts to make the same engage the cylinder the holes 51 in the belt to the skin, whereby the evenly throughout the length and width'thereof, > skin is positively evenly held on the belt and the skin being engaged by the lower ?ight 29 transportedtoward and into engagement with 15 of the belt, and the belt holds the: skinin engage‘?v , the springjy?ngers '60 which hold the same in ment with the cylinder I5 until the cylinder with the skin thus held thereon turns to a point where‘ the proper position for clipping of the hair there of byitheknives. As indicated by the numeral (ii the suction opening 56 extends down along the perforations suction pipe, l5whereupon register with the the suction opening in' the" in ' the back 'of the suction pipe 58 so as to retain the 20 suction pipe will strongly and evenly secure the suction ‘effect for. holding the skin until the skin to the‘ exterior of the cylinder so that all same hasipasse'd- the clipping position; and‘has unevenedges will be exactly held. The skin and’ alllparts'thereof thus held against the exterior of the cylinder by suction, is carried down under the tensioning ?ngers 35 until exactly in a posi tion to have theiur thereof “clippedby the cooperating knives 45 and 41. ~ ' - , .' Thearrangements are such’ that as the ' leading edge of the skin‘ passes the region of the 'clip ping, the same :will engage betweengtherbelt 2|" and the lower part‘ of the_cylinder;;and pass from the region of‘ the suction-opening :'to the bottom .of'the cylinder, the exact ‘position ing' of the skin being maintained by the.:portion of the ‘skin which is over the suction hole and that. portionof the skin preceding the same which is held in‘ place on the cylinder by the belt 2i; whereby the skin, throughout its oper ative engagement with the cylinder 15, is vheld in anexact, smooth,,and even contact with the drum, so: that absolutely uniform clipping 'of skin until - the skin has passed position. ' ' related 25 the \ , It is to be noted that neither the perforated cylinder l5northe perforatedbelt 51 has to-be perforated over its’ entire width- and length or‘ circumference,‘ but may be perforated only in 39; such portions, thereof as necessary to carry the leading edge ofthe skin past the clippingknives or cutters; the remainder ofthe' skin being then held to the cylinder or belt by the spring pres— sure ?ngers 35. Where-more than one type’ of work is tobe done by one machine,.shields of impervious material may be applied to a com-v pletely perforated cylinder or belt to’ close off the undesired perforations. - Although I have shown and described herein thexhair thereof throughout the length'and width preferred embodiments .of my invention, it is to be de?nitely understood that I do not desire to limit’the application of the invention thereto, of the skin is accomplished by passing the same once through the machine. The position of» the stationary knife 41 and of the rev‘oluble knives 45 may be altered7 to achieve the cutting of the hair materials, and in the structure and arrangement of the parts, ‘within the spirit of the invention and the scope of the subjoined claim. of the skin at-the desired length. * - ' .
