A method for packaging in block form a sheathed hot-melt adhesive product comprising the steps:
- (a) of continuously supplying a sheathed hot-melt adhesive product;
- (b) of immersing the sheathed hot-melt adhesive product in a liquid refrigerant;
- (c) of pressing the sheathed adhesive product at a portion thereof;
- (d) of ultrasonically welding the sheathed adhesive product at the pressed portion;
- and
- (e) of cutting the sheathed adhesive product into a block at the pressed portion.
A method for packaging in block form a sheathed hot-melt adhesive product comprising the steps:
- (f) of continuously supplying a sheathed hot-melt adhesive product;
- (g) of immersing the sheathed hot-melt adhesive product in a liquid refrigerant;
- (h) of pressing the sheathed adhesive product at a portion thereof;
- (i) of ultrasonically welding the sheathed adhesive product at the pressed portion, the welding and pressing steps using a sonotrode;
- and
- (j) of cutting the sheathed adhesive product into a block at the pressed portion, the cutting step being carried out at the same work station as the welding step and being concomitant with it.
A block of sheathed hot-melt adhesive product comprising:
- a hot-melt adhesive;
- and
- a sheath ultrasonically welded at two ends thereof, containing the hot-melt adhesive;
- the block weighing 0.5 kg or more and preferably 1.4 kg or more.
An installation for packaging a sheathed hot-melt adhesive product comprising:
- means for introducing a sheathed hot-melt adhesive product, upstream of a conveyor route of this product;
- refrigeration means comprising a liquid refrigerant, along the conveyor route;
- means for conveying the adhesive product along the conveyor route;
- means for pressing the adhesive product;
- means for ultrasonically welding the adhesive product;
- means for cutting the adhesive product;
- and
- means for synchronized control of the pressing and welding means;
- in which the pressing, welding and cutting means are immersed in the liquid refrigerant.
