The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered across the aperture, forming a window into the container. A window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device engages a container. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered to the inner surface of the body ply and has a portion extending across the aperture, forming a window into the container. The method involves providing a window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device that is adapted to release pressurized air into the container through at least one of the platens. The container is engaged between the platens in an airtight manner and, optionally, the container window is positioned adjacent the inside wall of the machine pocket. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

Regarding a cardboard sheet-cutting device, a cardboard sheet-cutting control unit and a cardboard sheet-manufacturing apparatus, continuous cutting is made during job changes, in which the cardboard sheet cutting width changes, without stopping conveyance of the cardboard sheets, by a printing unit for printing cutting marks on a double-faced cardboard sheet; a slitter scorer for cutting the double-faced cardboard sheet to a specified width; a cutoff for cutting the double-faced cardboard sheet to a specified length; a mark detector for detecting cutting marks; a movement unit for moving the mark detector along the width direction of the double-faced cardboard sheet; and a cutting control unit for performing control to actuate the cutoff on the basis of the detection results of the mark detector and moving the mark detector using the movement unit on the basis of job-change timing data and post-job change mark position information.

A method for making a paper straw and includes a step of applying anti-bacterial and water-proof layer to both sides of a paper sheet; a step of flatting or scrolling the paper sheet to be round and tubular, and two sides of each paper sheet being overlapped to each other; a step of pressing and adhering the overlapped portion to form initial type of a paper straw; a step of drying the initial type of the paper straw to solidify the water-proof layer, and a step of cutting the initial type of the paper straw into multiple sections. The paper straw of the present invention is anti-bacterial, water-proof and is not deformed in liquid or beverage.

A high-speed cornet bending machine with high production capacity and mechanically independent motion control system is provided. At least one feeding device is provided for transferring the sheets in order to the conveying device. Feeding device motors are provided for driving the feeding device. Conveying devices include a transfer line for transferring the sheets from the transport apparatus to the end bending unit as standard and end bending units for standard bending the product ends into a high production capacity and mechanically independent movement control system.

An apparatus and method for forming a tubular masking tape from a planar masking tape easily and quickly. The apparatus includes an elongated frame having a proximal end and a distal end. A tape head is coupled over the distal end. A tape roll of the planar masking tape can be mounted to the tape head. A roller ASSY is spatially positioned above the top side of the frame, wherein the roller ASSY includes an upper roller and a lower roller positioned one above another. A die is mounted over the top side of the frame spatially between the tape head and the roller ASSY. A leading edge from the tape roll is passed through a slot in the die and thereafter the curved leading edge from the slot is pressed between the rollers of the roller assy.

A bale of stock packaging material includes a continuous tube of paperboard material, the continuous tube of paperboard material being flattened and folded back and forth on itself into a fan-folded bale. The continuous tube of paperboard can be a single piece of paperboard with two opposed edges that are folded to overlap with each other. The paperboard material can include a corrugated layer. The opposed edges can be adhered together to form a single seam that runs lengthwise along the continuous tube of paperboard. The adhesive can be applied between the two edges which can join to form the single seam.
