Abstract: A device for producing film includes a die defining a die outlet through which molten polymer is extruded. The polymer is suitable for producing one of a pre-stretch film and a conventional stretch film. The device includes a film producing device spaced apart from the die. One or more coolant supplies are positioned proximate the film producing device for directing a stream of coolant onto the molten polymer positioned on the film producing device and/or between the die and film producing device, for producing film having strips of increased thickness.

Abstract: A film processing apparatus includes a film delivery section and a film stretching section. The film stretching section is positioned downstream of the film delivery section. The film stretching section defines a first inlet and a first outlet. The film processing apparatus includes one or more slitting devices positioned between the first inlet and the first outlet.

Abstract: A device for producing pre-stretch film includes a die defining a die outlet through which molten polymer is extruded. The polymer is suitable for producing the pre-stretch film. A film producing device is spaced apart from the die. One or more coolant supplies are positioned proximate the film producing device for directing a stream of coolant onto the molten polymer positioned on the film producing device.

Abstract: A method for maximizing a width of a pre-stretch film includes providing polymer being suitable for producing the pre-stretch film. A pre-stretch film having strips of increased thickness is produced. The method includes coordinating a thickness of the strips of increased thickness with a formation of edge thickening caused by neck-in during stretching of the pre-stretch film.

Abstract: A turret winder for winding web material on spindle-supported cores has a turret which is moveable into three indexing positions, one of which is a web transfer, cutting and winding station, and another of which is a winding completion station. Frames adjacent to the turret support carriages which support a secondary lay-on roll. The carriages include a primary carriage which is moveable vertically with respect to the turret and a lay-on roll carriage which is moveable horizontally with respect to the primary carriage. The lay-on roll carriage has an arm which is engaged by the turret during movement of the spindle between the above two positions so that arcuate movement of the spindle is translated to movement of the lay-on roll carriage in such a manner that the lay-on roll accurately follows the movement as the building roll moves to the winding completion station.
