Method and apparatus for making a corrugated zone to a bendable drinking straw. The drinking straw is made of a web that is moved along a guided path in a wanted speed and the corrugated zone is created by clamping the web with a clamping mechanism against the guided path for a wanted period of time to stop the motion of the second part of the web after the clamping mechanism.

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.

A coating process of a segmented paper pulp bottle blank includes: S1, placing a film raw material into a bottle blank to be coated; S2, folding an upper edge of the film raw material to fix the upper edge onto a mouth of the bottom blank; S3, placing the bottle blank fixed with the film raw material into a coating mold; S4, placing a hot-air blowing pipe into the bottle blank; and S5, sucking air by the coating mold to absorb the bottle blank onto inner cavity walls of the coating mold, blowing in hot air by the hot-air blowing pipe to make the film raw materia1, after being heated and softened, to be expanded and adhered to the inner wall of the bottle blank, and finally opening the coating mold to take out a finished product. Moreover, a production process of a segmented paper pulp bottle is provided.

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.

A method of making a paper straw with a bend includes coating a strip of paper with polyethylene on a first side and a second side of the strip of paper; cutting the strip of paper to a desired length; providing a spring apparatus of a predetermined length; rolling the strip of paper around the spring apparatus such that the strip of paper partially overlaps with itself to form a straw, the polyethylene holding the strip of paper in a rolled position; applying steam to the straw; and bending the straw to create a bend, the straw remains bent; and removing the spring apparatus from the straw.

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.
