A B S T R A C T A hot press for treating a web of material (1) and comprising up- per and lower press platens (3, 4), upper and lower movable press belts (12, 13), an upper movable bed (14) of rods (16) arranged between the upper press platen (3) and the upper press belt (12), and a lower movable bed (15) of rods (16) arranged between the lower press platen (4) and the lower press belt (13), said press belts (12, 13) defining between them within the region of the press platens (3, 4), a pressing zone (22) having an entry section (23) for introducing the web (1). According to the invention an aligning and feeding means (35, 36) is arranged for each bed (14, 15) of rods (16) and comprises a wheel unit (37) arranged within the entry section (23) and comprising a rotatable shaft (38) jour- nalled perpendicularly to the direction of movement of the press belt (12, 13), and a plurality of wheels (39) secured to said shaft (38), said wheels peripherally supporting a plurality of short rollers (40). The rollers (40) of one wheel (39) are aligned with the rollers of the other wheels (39) to form rows of rollers (40) located transverse to the direction of movement of the press belt (12, 13) and having coinciding central axes (41). The rows of rollers (40) are brought into contact with the rods (16) recircu- lated to the entry section (23) in such a manner that, upon con- tact with one rod (16), one row of rollers (40) retards the move- ment of said one rod in relation to the press platen (3 and 4, re- spectively), thus packing the other rods (16) located next up- stream closely together, and then delivers said one rod (16) to the pressing zone (22) for free rolling.
