Claims17
An apparatus suitable for inserting a sizing disc into an unshirred end of a shirred tubular casing wherein the sizing disc has a larger periphery than the unstretched inner periphery of the unshirred end of said tubular casing which comprises in combination a frame, disc storage means and disc dispensing means positioned on said frame, securing means associated with said dispensing means adapted to detachably secure an unshirred end portion of a shirred tubular casing to said dispensing means, disc advancing means communicating with said dispensing means for advancing said sizing disc disposed in planar relation to said dispensing means in a direction substantially parallel to the longitudinal axis of said dispensing means and said unshirred portion of said tubular casing and into said unshirred end of said tubular casing, and disc rotating means for rotating said disc in said unshirred portion in a direction perpendicular to the longitudinal axis of said tubular casing.
A method for inserting a sizing disc into an unshirred end portion of a shirred tubular casing wherein the sizing disc has a larger periphery than the unstretched inner periphery of the unshirred end of said tubular casing which comprises, unshirring an open end portion of a shirred casing length, positioning at least a part of said unshirred open end portion of casing length around an exit of a sizing disc dispenser, securing said unshirred open end portion of casing length to said exit, inserting a sizing disc into said unshirred end portion such that the plane of the disc is parallel to the central longitudinal axis of said secured unshirred casing, rotating said disc through about 90.degree. while advancing it through said unshirred casing end portion, stretching locally said unshirred casing through said simultaneous rotation and advancement of said sizing disc, continuing the advancement of said disc into said unshirred open end portion of said casing and positioning said disc a predetermined distance from the shirred portion of said casing length with the center of said disc coincident with the center of said unshirred casing and with said unshirred casing stretched about said disc, and thereafter releasing said secured portion of said unshirred casing from said exit.
A method for inserting a sizing disc into an unshirred end portion of a shirred tubular casing which comprises, unshirring an open end portion of a shirred casing length, positioning at least a part of said unshirred open end portion of casing length around an exit of a sizing disc dispenser, securing said unshirred open end portion of casing length to said exit, inserting a sizing disc into said unshirred end portion such that the plane of the disc is parallel to the central longitudinal axis of said secured unshirred casing, rotating said disc through about 90.degree. while advancing it through said unshirred casing end portion, continuing the advancement of said disc into said unshirred open end portion of said casing and positioning said disc a predetermined distance from the shirred portion of said casing length with the center of said disc coincident with the center of said unshirred casing, and thereafter releasing said secured portion of said unshirred casing from said exit.
