Roller-type press 1, with reticular frame 3, resting on a horizontal frame 5 which extends beyond the base 7 of the frame 3, to which frame 5 a structure 9 with a single L- beam is applied, resting with one side 11 on said frame 5 and with the other side 13 free; said single beam 13 having a longitudinal slit 19, in depression, and a plurality of rollers 23, placed idle downstream from said slit; another plurality of rollers 27, parallel to the first, in pressure, another top section 29 being envisaged parallel to the section 31 of the first rollers; said section 29 rising and falling on the first section 31 by means of pneumatic pistons 33; a special motor 37 driving said pressure rollers 27 by means of special pulleys 41. The edges 47 of the belt are positioned on the slit in depression 19 and from here, kept in position by the depression itself, sent between the pressure rollers 27 and the rollers 23 where pressure and heat complete the junction. <IMAGE> |
