Operating in the plastics machinery market since 1975, today BFM is one of the main Italian players in the production of take-offs & winders for blown film lines (as partner of Luigi Bandera), flexographic printing units with central drum (up to 10 colours) and stack-type (2-4-6-8 colours) and automatic bagmaking machines.
The company attended Plast 2018 with some accessories of its top printing machine - the 8-colour Marte central drum gearless model - designed exploiting the proven application experience from Bosch Rexroth, the industry leader in automation of printing and converting machines. This model is available in different printing widths; the standard repeat length ranges from 350 up to 800 mm (or 1200 mm for Plus Model) and the highest output speed is 400 m/min.
During the exhibition, one of the latest innovations in flexoprinting was on display: a line for printing, gusseting and embossing of FFS (Form-Fill-Seal) tubular film. The heavy duty sack is obtained from a gusseted or flat tubular film with an embossed area. It is normally used for polymer granules, fertilizers, salts, bulk goods, composts. This line is composed of a motorized unwinder suitable for reels up to a 1500-mm diameter, a flexoprinter with 2-4-6-colours (according to customer needs) and 800-mm width, gusseting and embossing units and finally a W400 single-station automatic winder with 800-mm width. It can be also equipped with corona treatment (refreshing or total), automatic web guiding units and micro-perforators.
As for the bagmaking machines, the special line on display is suitable for the production of “sac-a-poche” collected in rolls. It is a pastry-bag with triangular shape, made of a special, very elastic coextruded material (3 layers, 90-100-micron thick). The production process starts from a reel of tubular film; a double nip-roll (needed for tension control of such material) is followed by a station for inclined pre-cut and sealing, placed on the accessory section of the machine. A further station in the main machine provides for transversal cold pre-cutting.
The collection is made by a “mini-roll” equipment that winds up the bag in rolls (100 to 200 bags each) that can be packed through a conveyor. The production output is approximately 100 bags per minute. The machine base, model BM180, is used also for other applications (e.g. soft handle bags, patch handle bags), but all the accessories have been designed just for the sac-a-poche, according to the customer’s inputs.
