摘要:
Systems and methods are disclosed for starting a strip material in a substrate processing machine wherein the machine is not stopped and operators do not have to reach into the running machine to start the strip material. Exemplary systems include a strip material guide apparatus including at least one guide arm and at least one gas stream generator configured to direct strip material from the guide arm into a nip point of a substrate processing machine to join the strip material with the running substrates. The gas stream generator is operable to cause a leading end of a strip material dispensed from the guide arm to be conveyed via a gas stream toward the nip point or toward the running substrates, such that the leading end of the strip material becomes engaged by the substrate processing machine at the nip point and the strip material joins with the running substrates.

A method of making reinforced cartons comprises the steps of advancing a length of carton material along a path and progressively laminating at least one ribbon of reinforcing material to the advancing length of carton material. The ribbon of reinforcing material generally has a width less than the width of the length of carton material and is applied with adhesive at a selected location(s) across the width of the length of carton material. The web and its laminated ribbon are cut into sheets of a predetermined size and the sheets are die-cut and scored with fold lines to form carton blanks. The fold lines may transition from non-reinforced to reinforced portions of the blank and a special transition zone is contemplated to accommodate the transition. The carton blanks are subsequently formed into cartons for receiving articles, the laminated reinforcing material providing reinforcement in selected portions of the cartons. Multiple ribbons and multiple layers of ribbons may be laminated to the web in respective selected locations to provide reinforcement in more than one portion of the cartons. Reinforcing ribbons may be deformed or altered to exhibit, for instance, corrugations or perforations prior to being adhered to the base sheet.

A method of making reinforced paperboard cartons comprises the steps of advancing a web of paperboard along a path and progressively laminating at least one ribbon of reinforcing material to the advancing web of paperboard. The ribbon of reinforcing material, which also may be paperboard, has a width less than the width of the web of paperboard and is applied with adhesive at a selected location across the width of the web. The web and its laminated ribbon are cut into sheets of a predetermined size and the sheets are die-cut and scored with fold lines to form carton blanks. The fold lines may transition from non-reinforced to reinforced portions of the blank and a special transition zone is contemplated to accommodate the transition. The carton blanks are subsequently formed into cartons for receiving articles, the laminated reinforcing material providing reinforcement in selected portions of the cartons. Multiple ribbons and multiple layers of ribbons may be laminated to the web in respective selected locations to provide reinforcement in more than one portion of the cartons. Reinforcing ribbons may be deformed or altered to exhibit, for instance, corrugations or perforations prior to being adhered to the base sheet. Reinforced cartons and carton blanks made by the method also are provided.

The present invention concerns a method of splicing two sealing strips and a sealing strip formed by the method. The sealing strip is placed at longitudinal edges of a packaging material web, used for packaging containers for liquid foods. The sealing strips to be spliced are cut each forming an oblique edge of about 45°, as seen in plan view. The oblique edges are then placed one on top of the other forming an overlapping area. The overlapping area is in the form of an oblique band having a length of about 3 mm. The ends of the sealing strips are then fused together by heating both from one side at the overlapping area.
