    Abstract: This invention forms a loose fill packing material comprising clean, elongated strips of paper formed from corrugated cardboard having internal fluting formatted to expand in height, improving the ability of the strips to lattice. A vertical slitter divides cardboard into blanks of a predetermined width generally with the grain of corrugation. The blanks are fed into a shredding device that cuts the blanks with a scissor motion across the width of the blank. The strips pass onto a cleated perforated conveyor and into an enclosed suction housing. Inside the suction housing is a vortex box enhancing air flow for cleaning the strips. Strips are centered on the conveyor. The strips move from the conveyor to an angled, vibrating sifter plate into a collector. Strips are sprayed with a liquid material having microbicidal, sanitizing, insect repellant, disinfectant and/or deodorizing properties.

  • Patent number: 6635004
    Abstract: An apparatus and method for removing cutout material that is at least partially severed from a web has a vacuum passage for drawing a vacuum, and a vacuum inlet plate connected to the vacuum passage. The vacuum inlet plate has an inlet edge defining at least part of an opening into the vacuum passage. The inlet edge has first and second angled edge portions that converge at first and second angles relative to the machine direction, respectively, to meet at a vertex portion. The vertex portion constitutes the rearmost portion of the inlet edge relative to the machine direction.

  • Patent number: 6589148
    Abstract: The invention is a moveable presser rail assembly for supporting blanking material during operation of a blanking tool for making packaging blanks. The moveable presser rail assembly includes a mount housing having a cavity that pivotally secures a pivot sleeve, and a guide strut is secured within the pivot sleeve by a spring biasing mechanism so that a fastening end of the guide strut may be rigidly secured to a presser rail. Because the guide strut may pivot within the mount housing, the presser rail may be rigidly secured to the guide strut and still provide reciprocating and non-parallel or limited lateral motion relative to a support plate that supports the mount housing.

  • Patent number: 6520900
    Abstract: Methods for setting-up a female blanking die for a die cutting machine for die cutting and/or blanking a carton blank, and universal press frames for use in such setting-up are all provided herein. The first stages in the erection of the female blanking die, which includes a rectangular framework of a front rail, a rear rail and two side rails, involve accurate placement of a template within the rectangular framework. All the rails are provided with a dovetail groove along its inside edges. This is achieved by the use of centre line orientation cylinders on a template, a centre line rod through aligned holes in the centre line orientation cylinders and centre line brackets at the precise centre point of the front and the rear rails. The template is mounted atop the centre line brackets by means of the centre line rod and rests loosely on template corner locking clamps.

  • Publication number: 20020160898
    Abstract: A presser assembly for supporting blanking scrap during a blanking operation is provided. The presser assembly includes a support rail; a presser rail connected to the support rail; and a connecting rail connecting the presser rail to the support rail and being adapted to pivot with respect to at least one of the support rail and the presser rail through a predetermined pivot angle range for changing a distance between the support rail and the presser rail. By pivoting, one can thereby selectively affect a folding and an unfolding of the presser assembly during a blanking operation.

    Abstract: Packaging machine, in particular for cigarettes, having subassemblies and elements for handling packaging material and cigarettes. In order to reduce the outlay on servicing for the packaging machine, the practice, in the region where dust and material particles occur to a pronounced extent, is for air to be extracted constantly or temporarily by suction, the particles being carried along in the process. Furthermore, particles adhering to articles, in particular to material webs, may be processed mechanically, in particular by brushes (41, 42), in order for particles to be detached and extracted by suction.
