ABSTRACT:
The invention relates to conveyor apparatus comprising substantially parallel conveyor belts, and seeks to provide such apparatus with means for reliably holding pieces of material fed seriatim to the apparatus on the conveyor belts. According to the invention, the belts (6) extend over a casing (10) which is formed with openings (12) forming elongate slits extending between the belts (6). In use, the negative pressure is created in the casing (10), and suction holds the pieces of material to the belts. The openings may be selectively closed by shutters (16) to adapt the effective suction area in accordance with the pieces (3) of material on the belts (6).
