A method of plastic film coreless roll removal from a spindle, comprising pushing of the plastic film coreless roll from the spindle with a perforated wall, where pressurized air-water mixture is fed at pushing the roll, providing expansion of the inner diameter of the roll. The object of the claimed technical solution is to provide technical results, consisting in reduction of power consumption by decrease of compressed air flow rate, with simultaneous increase of speed and safekeeping of the roll at its removal from the spindle by reduction of friction between the internal roll surface and the spindle surface.

The invention relates to a coil-transporting carriage with adjustable retaining arms and to a method for the reliable handling of metal coils of small external diameter, or of sleeves, on a coiler mandrel. The coil-transporting carriage has a vertically displaceable coil saddle for accommodating a coil or a sleeve, also has two retaining arms for stabilizing the coil or the sleeve, the retaining arms being arranged opposite one another on the coil saddle and being pivotable by means of rotary drives, and additionally has a second drive unit for moving the coil-transporting carriage. For pulling off from a coiler mandrel, the coil saddle is positioned against a coil located on the coiler mandrel and the retaining arms are pivoted onto the coil. For pushing onto a coiler mandrel, first a sleeve is placed on the coil saddle of the coil-transporting carriage and is thereby guided by the retaining arms.

A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.

A dunnage conversion system includes a machine for converting a stock material (14) into a strip of relatively lower-density dunnage, a coiling mechanism (20) for winding the strip into a coil, a taping mechanism (22) for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism (24) for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface (70) between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm (126) that pivots to push the completed coil off the coiling mechanism.

An apparatus (10) for folding sheets (17) and corresponding method, comprising at least a conditioning body (11), at least a folding unit (13) and at least an extraction mean (12) suitable to fold sheets (17) in sequence of variable formats, maintaining high cadences and at the same time simplifying the structure for the maintenance operations and/or format-changes.

A dunnage production system for producing coiled strips of dunnage includes a supply of strip-like dunnage, a coiler adjacent the supply and rotatable about a coiling axis for coiling a strip of the strip-like dunnage into a coil having a coiled configuration, and a tube aligned with the coiling axis. The tube has an internal diameter sized to receive the coil from the coiler in a discharge direction parallel to the coiling axis. The tube is capable of holding at least one coil in its coiled configuration until it is removed from the tube.

A roll body taking-out unit that takes out a roll body from a reel that holds a carrier tape storing components in a state of the roll body and stores the roll body in a case is provided. The roll body taking-out unit includes a separation unit that separates the roll body from the reel, and a roll body storage unit that stores the roll body separated from the reel by the separation unit in a case. Further, the roll body storage unit includes a case holding part that holds an empty case, and a chute part that stores the roll body separated from the reel by the separation unit one by one in the empty case held by the case holding part.

A method and apparatus for the production of coreless paper rolls, including a winding phase on a central spindle of a paper web carried out by a main reel, until the formation of a wound paper roll, a phase of extraction from the wound roll of the spindle by application of a relative axial extraction force between the roll and the spindle, where the winding phase includes a first winding phase of a number of web revolutions on the central spindle performed at a first winding tension that is lower than the next winding tension.
