output of freezer 24 which delivers the continuous sheet 23 of chilled pork sausage to the cutter unit chilled sheet 23 is directed to extrusion form 90 which includes base 90a and vertical sides 90b corresponding to the width of the continuous sheet the sheet is thus guided past a plurality of vertically suspended rotatable cutting disks 102 where the sheet is sliced into a plurality of equal width continuous lengths 104 of chilled material lengths 104 are then carried by conveyor 58 to an elongated vertical knife blade 106 which is reciprocated in a manner to be subsequently described in synchronism with a horizontal bed 108 a hold down roller 110 is disposed in front of blade 106 in order to hold the continuous links down during the severing operation by knife blade 106 a back board 112 is disposed over blade 106 as indicated above slicing of the continuous sheet 23 into a plurality of equal width continuous lengths 104 is accomplished by the action of rotatable cutting disks 102 as shown in fig1 disks 102 are rotatably assembled along horizontal bar 116 the ends of bar 116 are fixedly supported by a sleeve support member 118 which slidingly engages upper rod 120 sleeve member 118 is adapted with a collar 122 and rod 120 is adapted with a corresponding flange 124 to permit limited translation of sleeve 118 along rod 120 a compression spring 126 is assembled between the lower end of rod 120 and a seat 118a provided at the lower end of sleeve support member 118 compression spring 126 acts.
