摘要:
A method for manufacturing tubular bodies (1) exhibiting an inner circumferential surface and outer circumferential surface (8) for packaging tubes out of a strip-shaped film substrate (2) that encompasses a barrier layer (19) against moisture and/or oxygen, exhibits at least one weldable plastic layer (3), and comprises a beveled first edge face (5) extending in the longitudinal direction of the film substrate (2) and a beveled second edge face (6) spaced apart from the first edge face (5) by the width of the film substrate (2), wherein the first edge face (5) and second edge face (6) are arranged opposite each other with the formation of a tube shape, and welded together during exposure to heat, the first and second edge face (5, 6) are pressed against each other during welding so as to compress the barrier layer (19), accompanied by the formation of a wave geometry encompassing several wave peaks and/or several wave valleys and exhibiting at least three zero crossings and/or at least two equiphase zero crossings.

A method and apparatus for manufacturing recyclable paper pallets utilizes spool-shaped laminated supports which are wound on a spool-shaped mandrel utilizing adhesive coated paper strips. In one aspect of the invention, the spool-shaped laminated supports can be glued to conventional upper and lower pallet skin sheets also made of paper material, such as corrugated paperboard. In another aspect of the invention, the spool-shaped pallet supports are utilized in a system in which the pallet is integrated directly into a pre-strapped load. In this system, a slip sheet is strapped directly to the bottom of a load and the slip sheet is glued directly to the upper faces of an array of pallet supports, sufficient to support the load and to provide the spacers or standoffs for subsequent insertion of lifting equipment, such as a lifting fork, beneath the load. The inherent rigidity of the strapped load may be sufficient to compensate for the lack of rigidity of the thin paper slip sheet. If the supported load does not have adequate structural rigidity, a lower structural skin sheet may be glued to the lower faces of the pallet support array to provide the strength in compression needed to lift the palletized load. The system of the present invention provides wide flexibility allowing pallet systems to be utilized which are adequate to support the intended load with a minimum use of materials. The spool-shaped supports may be manufactured on-site and the pallets formed on the in-line system processing the material loads. An alternate pallet-support is made from a strip cut from a continuous web of single face corrugated paperboard.

A device for processing at least two webs of material made of paper or plastic film is provided with at least two rolls of material, each of which can be rotated in an unwind unit and from each of which a predrawing unit, comprising predrawing rollers or rolls, takes off the web and pulls it into the device. To guarantee the proper infeeding of the web into the device, even if after a sudden operating stoppage the rolls of material coast longer than the predrawing units, there is between each unwind unit and each predrawing unit one brake each, which decelerates the web and which is activated when the predrawing units are abruptly stopped or they significantly delay the infeed.

A paper stick-forming device which converts a paper sheet into a hollow stick suitable for lollipop handles, pencils, and other short stick applications. The paper sheet is first introduced into a cutoff device where portions having the proper length are cut from the sheet. Then the portions are curled by supporting them on a polyurethane covered roll and by passing them under a curling wire comprising a hard, thin cylinder of tungsten carbide. The roller which supports the curling wires also includes open circular recesses between each wire for storing the rolled paper portions until they are delivered to a belt conveyor.

A filter for a cigarette or other smoker''s article wherein loose material is held in separate layers by porous elements arranged between the layers and so arranged that smoke passing from one end of the filter to the other is constrained to pass across and through said layers in succession.

Tubes are contacted by belts on the upper portion of their outer surface to advance the tubes along a path paralleling their longitudinal axes with the lower well being slit and a guide subsequently being engaged to position the tube with its slot paralleling an edge of a sheet of jacketing material advanced toward the tube and positioned adjacent thereto whereby belts acting normal to the path of the tubes contact the upper portion of their outer surface to roll the tubes about their longitudinal axes to engage the sheet jacketing material wrapping it about the tube being rolled thereover.
摘要:
The uniformity of cigarette filters formed from coherent webs of filtration material is improved by feeding of the web about a convex idler roll just prior to feeding of the web into the garniture of a cigarette filter rod maker, and preferably feeding the web from the idler roll to the rod maker along the axis of the garniture.
摘要:
An improved skiving machine device and a new method for preparing and forming paperboard side seam blank providing it for a smooth edge which a roughened skived surface can fold around and adhesively secure to its adjacent surface forming a protected edge for the side seam flap of a paperboard container blank with contact being made between the roughened paper surface and the adjacent side seam flap giving good bond characteristics and accuracy.
