Title: Separation of animal intestines
Claims: What we claim is: 1. Apparatus for the separation of animal intestines comprising a horn member the leading end of which is solid and curved and the initial portion of which is adapted to receive therearound a portion of small intestine tube which has been initially severed from the stomach of a beast, said horn diverging after the solid leading end thereof into a trailing end comprising a plurality of rods, said rods being terminated and joined at their terminal points to a fixed bar, a rotary cutting device being positioned in relation to the curved solid leading end of said horn so as to sever the small intestine tube from the stomach portion of the beast as the tube is fed along the horn, there being a pair of pulling rollers positioned on either side of the solid portion of the horn adjacent the point where the horn diverges into plurality of rods, said pulling rollers being adapted to engage the small intestine tube as it is fed over the solid portion of the horn and to pull the tube over said solid horn portion, the rods of said horn being adapted so that the portion of intestine tube fed thereover is expanded beyond its normal cross-sectional area, there being provided adjacent the terminal points of the rods a plurality of rotary cutting members located so that the outermost rotary cutting members effect an initial severing of the expanded small intestine tube so to isolate therefrom that part of the tube containing the gold beater strand of the serosa membrane and the inner rotary cutting member or members sever the separated portion of tube containing the gold beater strand into a plurality of threads, two or more co-operating further rollers through which the severed threads may be fed so that the threads may be beaten between said co-operating rollers and the gold beater strand contained in each thread thus processed for collection, and guide means being placed relative to the cutting members which effect longitudinal severing of the small intestine tube itself so that that part of the small intestine tube which is not threaded by the innermost of said cutting members may be conducted away from the moving parts of said apparatus for collection, wherein said guide means comprise a weighted rod privotally secured to the solid portion of said horn and a hook-shaped member disposed beneath said weighted rod. 2. Apparatus as defined in claim 1 wherein said rotary cutting blade which is adapted to effect an initial severing of the small intestine tube from the stomach is provided with a housing, said housing having a recess therein exposing part of the rotary blade and wherein the curved leading end of the horn is located relative to said recess so that severing of the small intestine tube is effected by the rotary blade rotating in said recess. 3. Apparatus as defined in claim 2 wherein said housing has a second recess provided therein in order that the stomach of the beast with the small intestine tube affixed may be introduced to the rotating blade in said second recess in order to effect an initial severing of said small intestine tube from said stomach. 4. Apparatus as defined in claim 1 wherein said co-operating further rollers through which said severed threads are fed for beating comprise a smooth upper table roller and a pair of toothed lower rollers, the first of which is a control roller and the second of which is a beater roller. 5. Apparatus as defined in claim 1 wherein said apparatus is provided with a further final pick-off roller in order that gold beater strand threads proceeding from said co-operating further rollers may be fed over said final pickoff roller for collection. 6. Apparatus as defined in claim 4 wherein said pulling rollers are 2 inches diameter rollers driven to rotate at approximately 360 r.p.m., the smooth upper table roller is of 4 inches diameter and driven to rotate at 200 r.p.m., the control roller is of 3 inches diameter and driven to rotate at 265 r.p.m. and the toothed beater roller is of 4 inches diameter and driven to rotate at 1,250 r.p.m. Other info: Inventors: Evers, Roy James (Cronulla, AU) Perrett, Darcy Glen (Peakhurst, AU) Application Number: 518823 Filing Date: 1974-10-29 Publication_date: 1976-04-13 Assignee: Cyanamid Australia Pty.
