Abstract: A method for wrapping groups of products with stretch film comprises the following steps: forming groups of products having a front and a longitudinal dimension that follows a line of feed; placing a first wrapping on the group of products to form a package that holds the products together; expelling the package thus obtained along the feed line; turning the package through an angle of 90°; placing over the first wrapping a second stretch film wrapping on the package thus obtained, the second wrapping having at least one narrowed strap-like segment surrounding a part of the package. The invention also relates to an apparatus that implements this method and the package obtained using the method.

Abstract: A combined cutting blade and heat bar for use with a vacuum packaging device having a lid for sealing over the cavity of a base is disclosed. The cutting blade and heat bar are connected to one another and movable via a single actuating mechanism mounted to the lid.

After air evacuation, the combined mechanism is lowered with the heat bar heated, melting the bag closed behind the slitted area of the bag.

Abstract: An apparatus and method of enclosing material in a net and supplying a handle for ease of carrying the netted material, comprising clippers, irises, and a handle maker. A conveyor carries the material to a pair of irises. The irises gather the netting around the material, the first clipper cuts and closes the netting, and the handle maker forms a loop out of the severed netting. The second clipper attaches the loop back to the netting to form a handle. A scale can be used to weigh the material and a printer can create a label, with the weight or whatever other information is desired, for attachment to the netting.

Abstract: A bag manufacturing and packaging apparatus includes a bag manufacturing unit that tubularly forms a strip film and manufactures a bag filled with articles; a feed roller unit that feeds a strip, to which the bag manufactured by the bag manufacturing unit is mounted; and a mounting unit that mounts the bag to the strip fed by the feed roller unit. The strip is rectilinearly maintained between the feed roller unit and the mounting unit by imparting a bend on the strip in the transverse cross section that intersects a transport pathway of the strip. The object of the present invention is to provide a bag manufacturing and packaging apparatus that, even if the strip to which bags are mounted lacks rigidity, can smoothly feed the strip, automatically thread the strip to the mounting unit, and form appropriate slits in the strip.

Abstract: This invention relates to a system for the automated attachment of a carrying handle on product packages. The system incorporates devices for advancing the products, means for the forward-feeding of a foil-strip designed to serve as a carrying handle, as well as at least one rotating element, whereby the foil strip is guided over the rotating element in such fashion that a rotation of the rotating element causes each one end of the foil strip to be attached to opposite sides of the product package. According to the invention, the system employs at least one rotating element featuring at least three arms. Thus, in advantageous fashion, the throughput rate is augmented, and the length of the carrying handle is determined by the cove formed between each two arms of the rotating element.
