A method, apparatus and program product may utilize packaging material quality compensation to sense changes in certain characteristics of a packaging material that can be associated with increased risks of film breaks, and automatically make certain changes in machine settings to mitigate the impact of those enhanced risks.

There is provided a system for packaging objects on a conveyor using a hose-shaped stretch foil. More specifically, the invention provides a system, wherein the hose-shaped stretch foil can be wrapped around the objects in a horizontal manner.

A method, apparatus and program product are provided that utilize wrap profiles that specify controlled wrap cycle interruptions to handle specialized load requirements for loads to be wrapped by a stretch wrapping machine. Also provided is a method of creating wrap profiles, and a plurality of wrap profiles are stored in a database.

A control system for a wrapping apparatus may include a packaging material dispenser configured to dispense packaging material for wrapping a load. The control system may also include at least one sensor assembly configured to generate a signal based on instantaneous demand for packaging material at the load. The control system may further include a controller configured to control operation of the packaging material dispenser based at least in part on the signal.

A wrapping machine for wrapping a product with a plastic film includes a frame, a supporting ring rotatably supported by the frame and rotated around a wrapping axis by a driving device, an unwinding unit fixed to the supporting ring and supporting a reel of film, pre-stretching rollers rotating about longitudinal axes and cooperating with each other to unwind and stretch the film, and a pre-stretching motor fixed to the frame and coupled to, and arranged to rotate, the pre-stretching rollers through a respective transmission assembly. The transmission assembly includes a driving ring rotatably supported by the frame and rotated about the wrapping axis by the pre-stretching motor through a friction roller, and a driving belt wound around, and rotated by, the driving ring and coupled to one pre-stretching roller to rotate the pre-stretching rollers when the driving ring is rotated by the pre-stretching motor.

An apparatus for wrapping a load may include a film dispenser for dispensing a film web including a film dispensing drive. The apparatus may also include a rotational drive system for providing relative rotation between the load and the dispenser during a wrapping cycle. The apparatus may further include a controller configured to operatively couple the film dispensing drive and the rotational drive system such that, for any portion of a revolution of the film dispenser relative to the load during the wrapping cycle, the film dispenser dispenses a selected length of the film web corresponding to the portion of the revolution.

The invention relates to a device for processing at least one packaging container, in particular for stretching out at least one stretching element of the packaging container, comprising at least one pivoting-arm pair, which comprises a first pivoting arm and a second pivoting arm, which is arranged in a mirror-symmetric manner in relation to the first pivoting arm with respect to an axis of symmetry perpendicular to the at least one linear axis, wherein the first pivoting arm is supported in such a way that the first pivoting arm can be rotated about a first pivoting-arm axis of rotation perpendicular to the axis of symmetry in a first rotational motion and can be displaced in the direction of the at least one linear axis in a first displacement motion and the second pivoting arm is supported in such a way that the second pivoting arm can be rotated about a second pivoting-arm axis of rotation perpendicular to the axis of symmetry in a second rotational motion and can be displaced in the direction of the at least one linear axis in a second displacement motion, and comprising a coupling transmission, which is designed to produce the first rotational motion and the first displacement motion of the first pivoting arm and the second rotational motion and the second displacement motion of the second pivoting arm from at least one first driving motion and one second driving motion, and wherein the first rotational motion and the second rotational motion are synchronous to each other and in opposite directions and the first displacement motion and the second displacement motion are synchronous to each other and in opposite directions.

An unpacking system having a folding-out device for folding outwards an initially folded-in packaging portion of an item of packaging for an object, and having a stretching device for stretching an item of packaging for an object. The item of packaging herein is in particular a pouch, and the object is in particular a pharmaceutical or cosmetic object. The unpacking system furthermore has a transportation installation for transporting the object in a transportation direction. The packaging portion in the stretching device is stretched parallel with the transportation direction. A filling system is disclosed having such an unpacking system, and methods are disclosed for folding outwards, for stretching, and for unpacking.

An unwinding apparatus (1) for wrapping machine (100) to wrap with a film (50) a load (30) on a pallet (40), comprising supporting means (2) for supporting a reel (60) of film (50), roller means (3, 4, 7) for unwinding and pre-stretching the film (50) and a guiding roller (6) that can be tilted for reducing a band width of the film (50) and/or deviating it towards the; first driving means (10) for continuously tilting the guiding roller (6) in a plurality of operating positions (P0, P1, P2) along an adjustment stroke; the guiding roller (6) comprises a first end portion (16) rotatably connected to the supporting means (2) and provided with a roll (8) able to roll up a longitudinal lower edge (50a) of the film (50) when the guiding roller (6) is tilted to form a longitudinal rolled portion (51).

A method, apparatus and program product utilize curve fitting to control a dispense rate for a packaging material dispenser. Predicted demands at a plurality of rotational positions of a load relative to a packaging material dispenser may be used to generate one or more points to which a curve may be fit, such that dispense rates may be determined for rotational positions between those for which predicted demands have been determined using the curve.
