Abstract:
A folding device for blanks has the shape of a removable module with an integrated securing device for securing the module in the frame of a machine. The module has two series of pulleys, which have a common drive drum and provide a path for a first belt having an upper twisted folding path and a second belt having a lower planar part. The drum is provided with a connecting element to connect the drum directly to a shaft normally provided to drive a gluing wheel which the module replaces.
Abstract:
A manual feed machine for the application of tabs to sheet stock has a strip feeder for feeding a foil strip into the path of a sheet which is manually insertable beneath the cutter for the file strip to entrain a previously cut segment into the heating jaws. A die cutter downstream of the foil application can cut the tab after the jaw opens and the sheet is transported to the cutter. Only after the perimeter of the sheet has cleared the blade, is the previously advanced foil strip cut to form the next segment.
Abstract:
A carton blank folding and gluing system having a feeder unit, a variety of units, a gluing unit, a stacking unit and belts for continuously conveying carton blanks to the units. The carton blanks are of various types and sizes. The system operates to move only the attachments required for folding or gluing the carton blank to predetermined positions in the units and to retract attachments not required for folding or gluing the carton blank. A control device is provided, in which the predetermined positions of all of the attachments required for folding or gluing the carton blank are automatically determined, stored and outputted by receiving a signal representative of the type of carton blank and signals representative of the dimensions of particular parts of the carton blank.
