Abstract: A system and method for making bags in a continuous in-line process includes a central processing unit and a camera oriented to take an image of a bag based on a triggering signal. The camera provides an image to the central processing unit. The central processing unit is programmed to process the image and calculate a timing signal based on the image. A cylindrical rotatable drum having at least one seal bar provides a triggering signal to the central processing unit, to trigger when the camera should take the image. A perforation knife is controlled by a servo drive. The perforation knife is downstream of the drum. The servo drive receives the timing signal for activating the perforation knife from the central processing unit. The CPU uses the image and based on the distance between the seal region and the perforated line, counts pixels to result in an actual pixel count. The CPU then calculates a pixel count error by subtracting the actual pixel count from a predetermined pixel count setpoint.

Abstract: A hinge is disclosed for a plastic film. This film has a predetermined thickness sufficient for the plastic film to remain planar in an absence of a first bending moment applied across the plastic film. The hinge includes at least one linear groove configured in the plastic film to reduce the predetermined thickness of the plastic film at the linear groove. The hinge permits preferential hinging of the plastic film at the linear groove responsive to a bending moment at the linear groove across the plastic film less than the first bending moment. The linear groove has insufficient depth to sever the plastic film and enables the hinge film to retain sufficient remaining thickness at the linear groove to permit hinging and not tearing of the plastic film at the linear groove. When the hinge is placed across a plastic film, and the film bent at the hinge, the film defines a first panel and a second panel with each panel disposed at an angle to one another at the hinge.

Abstract: The embossing process is effected between a pair of embossing rollers provided with toothings of the same kind which comprise rows of pyramidal teeth extending in the axial and the circumferential directions. Compared to the theoretical pyramid shape, the heads of the teeth are flattened while the edges of the pyramids are cut. The rollers, which are mutually displaceable in the axial direction, are thus able to catch in a stable mutual position of maximum penetration and to remain in this position in operation. This allows a safe mutual synchronization of the rollers and an optimal embossing of any kind of materials, especially of paper foils.
