Apparatus for splicing of a continuous packaging web

An apparatus for adhesively splicing a terminal end portion of a first web section to a starting end portion of a second web section to form a continuous packaging web having regularly spaced packaging bulges on one surface, comprising:

• braking means for braking the terminal end portion of said first web section at a braking position located on a conveying pathway of the web, said braking means including a braking and positioning roller disposed to contact the belt-shaped product between the bulged sections at regular pitch intervals;
• and driving means activated in response to signals from said detection means for driving said braking means, wherein said braking and positioning roller freely advances and recedes at the conveying pathway via spring means;
• detection means coupled to said braking means for detecting the terminal end portion of the first web section;
• positioning means including interacting means for interacting with and moving the bulged sections in the conveying direction, said interacting means being driven diagonally relative to the conveying direction of the belt-shaped product, wherein said positioning means positions the terminal end portion at a prescribed position downstream from the braking position on the web pathway by tensioning and positioning the terminal end portion with interactive movement between the bulged sections and said interacting means;
• cutting means for cutting and separating the terminal end portion of said first web section and, forming a new terminal end portion, said cutting means cutting and separating the terminal end of the first web section by movement of a mobile cutting piece,
• starting-end positioning means for positioning the adhesively-covered starting end portion of the second web section, said starting end positioning means being located adjacent to said braking means, and including a cutting section to cut the starting end of the second web section between adjacent packaging bulges, and including a suction means for positioning the adhesively-covered starting end portion by suction against a retaining surface,
• retaining means for retaining the position of the new terminal end portion and for orthogonally displacing it in a conveying direction and pressing and connecting said new terminal end portion onto said starting end portion of said second web section;
• a mobile cutting piece which reciprocates orthogonally relative to the conveying direction, said mobile cutting piece having multiple slots of a prescribed pitch disposed to accommodate the bulged sections, and
• a pressing means for moving said new terminal end portion into adhesive connection with said starting end portion.
