A method, a packaging system, and use for packaging objects on a conveyor using a hose-shaped stretch foil of plastic material. A method, system, and use, where the hose-shaped stretch foil may be stretched around the objects in a horizontal manner. The packaging system comprises a first conveyor and a second conveyor where first and second conveyors are arranged for conveying objects from said first conveyor to said second conveyor. The system comprises a foil dispensing mechanism arranged in a space between the first and the second conveyor, and being arranged for dispensing a continuous hose-shaped foil onto said conveyed objects. The method comprises the steps of: conveying a first object and a second object via the first conveyor in a first conveying direction towards said second conveyor; conveying the first object through the foil dispensing mechanism, hereby arranging the hose-shaped foil onto the first object; conveying the first object from the first conveyor to the second conveyor; and conveying the second object in a direction opposite the first conveying direction by a predefined distance, hereby arranging an equal distance between said first object and said second object in said space between said first conveyor and said second conveyor.

The present invention concerns a device and method for reefing a portion of tubular film, the reefing device having at least one reefing finger and at least one drive unit. The drive unit has advancing means, which, for reefing the portion of tubular film, is brought into operative connection with the reefing finger at least at the height of a point of engagement, while enclosing the portion of tubular film, and moves the portion of tubular film in relation to the reefing finger. The device according to the invention and the method according to the invention are distinguished in particular in that the position of the at least one point of engagement can be changed along the reefing finger as reefing progresses or the position of the point of engagement on the reefing finger is changed.

A spool (10) for storing film for a waste storage device includes a core (12) and a flared funnel portion (14). Film is stored on the core (12) and can be retained in place by shrink-wrapping (34) as a result of which the core can be formed without an outer wall or base, reducing material and moulding costs.

An article packaging apparatus with a cylindrical cassette having a tube made of resin fitted on the outer peripheral surface thereof is mounted below a charging station for charging articles. Heated press heads for heating and fusing the resin tube are arranged below the cassette. The heated press heads are moved from a standby position remote from the resin tube to a clamping position for clamping the tube. The heated press heads are then lowered a predetermined distance from the clamping position in order to pull the resin bag and move the heated press heads to a fusing position for fusing said tube. The heated press heads are lowered a short distance from the fusing position and the heated press heads are moved to a separating position for separating an individual bag from the resin tube.

An apparatus for winding a flexible thin-walled tubular material, radially of itself into a plurality of overlapping reverse pleats for storage and subsequent unwinding or feeding comprises: a hollow guide member and means for supporting the guide member for rotary movement, a support member, and means for supporting the member for rotary movement, a supporting means permitting longitudinal movement of at least one of the members relative to the other, means for rotating the guide member and support member in opposite directions, and means for moving either the support member or guide member or both longitudinally and reciprocally whereby the support member is reciprocated into and out of the guide member. When flexible tubular material is passed over the guide member and secured to the support member, the rotary and reciprocal movements of the members are effective to cause the tubular material fed thereover to be wound in a plurality of overlapping reverse pleats.
摘要:
A banding apparatus for opening a substantially continuous ribbon of flattened flexible tubular material such as cellulose and severing that opened material to the desired length. Such apparatus includes a roll supported floating material which is actively positioned for internal engagement with the material by a pair of driven feed rollers. An electronic or similar control system synchronizes the feeding, cutting and positioning of an article to be enclosed by the severed sleeve of material.

The invention provides a diameter reducing system for reducing the diameter of a flexible container as the container is filled. The system includes a stretching device to stretch the container at the fill level as the container is filled with a plurality of particles. The stretching device can release a stretched portion of the container substantially at the fill level as the fill level rises. The container can be a flexible, elastic bag. Shrinking of the container at the fill level as the container fills promotes supporting engagement between particles to enhance the structural integrity of the filled container and to reduce the likelihood that particles will be damaged during movement of the filled container.
摘要:
Based on a conventional installation including a stuffing-portioning machine (1) and a fast clipper (2), duly synchronised, between which is established a shaping device (3) that converts the film (5) meant to wrap food products that is supplied in the form of a coil into a tubular element that can be coupled to the stuffing tube (3), on which is coaxially mounted a second tube (8) bearing an external casing (9) based on a tubular net, the invention consists of using tubes (4) and (8) with a small diameter, much smaller than that of the finished product, so that the film (5) is adapted to the tube (4) after the former is profusely folded longitudinally, while the small diameter of the tube (8) allows the multilayer shirring of the tubular net (9), using the pressure provided by the pumping system of the stuffing machine (1) to achieve the radial expansion of the film (5) and the tubular net (9) to obtain the final diameter of the finished product, which will vary according to the speed with which it is separated from the double clipper (2) carried by a conveyor belt (12) with an adjustable speed.
