The PA 035L automatic packing machine is a device designed to pack tight large elements such as doors, windows or furniture elements in shrink film.
Elements to be packed are placed by hand (or come on the line) on an infeed conveyor which while conveying them behind a transverse sealing bar wraps them in film unwound from two rolls by upper and bottom film unwinding mechanisms. A longitudinal sealing bar seals and cuts the film along the length of the package. The package comes on a belt conveyor to the area where the transverse sealing bar operates and is arranged centrally with respect to the sealing bar. The film is sealed along the top of the element (right side of the film). Then, the belt conveyor is lowered, the package is put on rolls which are activated and the package in the film comes so that the other end is in the area where the transverse sealing bar operates. The package is closed from the bottom (left side of the film). The package wrapped in the film moves on the rolls towards a heat shrink tunnel, for example, TGW 30/130.
The packing machine is equipped with a system of automatic unwinding of film from an upper and bottom roll, a longitudinal sealing bar and a transverse sealing bar, speed control of a conveyor belt and of a roll conveyor and speed control of a belt conveyor.
