The invention relates to a device for forming sleeve-like foil envelopes from a continuous flat strip of a sleeve-like foil material, comprising supply means (12) for supplying the continuous flat strip of sleeve-like foil material (1), cutting means for making a cut in this strip of sleeve-like foil material over the full width thereof so as to obtain the individual sleeve-like foil envelopes, as well as discharge means (20a-20b) for discharging the individual sleeve-like foil envelopes from the device. The device of the invention is characterized in that the device comprises rotational element means (20′) arranged for imparting a rotary motion during operation to the sleeve-like envelope to be discharged from the device. By imparting a rotary motion to an individually formed sleeve-like foil envelope while it is being discharged from the device it is achieved that the foil envelope will remain open, making it possible to place the envelope round a container in a simple and effective manner.

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 control device for a tubular material package is provided which achieves control of a tubular material package by the effective cooperation of relays (44), sensors (27) and a controller (60). All of the relays have an ON state and an OFF state and are connected to the controller, and each relay is connected to a corresponding component. The sensors are distributed on the components, and capable of detecting and identifying the current state of an object to be detected; all of the sensors are connected to the controller and send sensing information to the controller. The controller comprises electronics and a control program, and is capable of receiving the information from the sensors and sending instructions controlling the relays. The control device is used in a packing machine for tubular materials.

An apparatus for unfolding folded plastic film having a first side joined to a second side along a longitudinal folded edge for use in forming a packaging tube. The folded film travels through a slot and the folded sides are separated at their respective outer longitudinal edges. The longitudinal left side is conveyed toward and over a guide plate left side edge and then over a left form tube section. The longitudinal right side is conveyed toward and over a guide plate right side edge and then over a right form tube section. The longitudinal middle section including the longitudinal folded edge and part of both the first and second sides adjacent the longitudinal folded edge is conveyed toward and over guide plate angular edges and then onto a carrying surface.

The invention describes a machine for forming, filling and sealing (FFS) sacks (8, 11). As device characteristics, it covers an unwinding device (19) for a plastic tube (15), a cross-cutting device (17) that cuts the tube perpendicularly to its principal axis of symmetry and creates tubular pieces in the process, a bottom forming means (13) for forming a sack bottom at one end of the tubular piece, transport equipment (4, 10, 18) to transport the resulting sacks through the machine, a filling station with a feeding element (2) for filling the product (24) in the sack (8, 11), means (3, 4, 5) of reducing the distance between the product discharge opening of the feed element and the bottom of the sack to be filled as well as sealing means to seal the filled sack. In this context, the means (3, 4, 5) of reducing the distance between the product discharge opening (31) und the bottom of the sack to be filled covers a sack lifting device (3, 4, 5) with which the sack (8, 11) can be lifted in the filling station in such a way that its upper edge (25) is located above the product discharge opening (31) of the feed element (2).
摘要:
The invention relates to a method and a system for packaging at least one object in film (1), wherein the film is tubular and preferably made of plastics. Novel aspects of the invention comprise that a piece of film is prepared with a number of wrinkle-shaped folds, following which the piece is processed to bag-shape by welding of the film and cutting it off the remaining part of the film, following which the bag-shaped film with folds is arranged to receive the object, following which the object is introduced interiorly or the film.
