To fold a piece of linen (5) to a very small final dimension, for example a bed sheet to 9″×6″, said piece of linen is kept constantly under pressure after final folding until it has been fixed in a storage position, in order to prevent opening of said final fold. This can be effected by pushing it during final folding by means of a folding sword into a receptacle (20), from where it is pushed by means of a ram (26) onto a stacking line (27) where its outer surfaces each rest against a corresponding outer surface of an adjacent piece of linen (5′) or another stop surface formed by slides (31a,b) or a pressure plate (33), so that it is fixed in its final configuration. Alternatively, the piece of linen can be fed, while maintaining pressure on the outer surfaces, to a packing apparatus and surrounded there by a strip of packaging material.
Process for the automatic final folding and subsequent storage of a piece of linen (5), in which final folding leading to a final configuration having a first outer surface and a second outer surface parallel thereto is carried out under the action of forces which are directed essentially towards one another at the end of the final folding and exerted on said outer surfaces, and thereafter transfer to a storage position is effected for storage or intermediate storage, characterized in that the transfer of the wash piece is effected while maintaining the forces acting against the outer surfaces at the end of final folding, until it is fixed in the final configuration in the storage position by stops acting against the outer surfaces.
Final folding means having a first draw-in belt (2) and a second draw-in belt (3), which form a draw-in surface (4) interrupted by a gap (6), and having a folding sword (15) which can be advanced and withdrawn through the gap (6), characterized in that said means comprises a transfer device (16) arranged, in a starting position, directly at the gap (6) and on the side opposite the folding sword (15), having a first stop surface (23) and a swivellable or displaceable second stop surface (24) parallel thereto, which between them form a receptacle (20) for receiving a piece of linen (5).
Final folding means having a first draw-in belt (2) and a second draw-in belt (3), which form a draw-in surface (4) interrupted by a gap (6), and having a folding sword (15) which can be advanced and withdrawn through the gap (6) and having a folding channel (36) which is formed between two belts and emanates from that side of the gap (6) which is opposite the folding sword (15), characterized in that said means comprises a packing apparatus (37) having a pair of packing belts (42, 43) which between them form a packing channel (41), whose width approximately corresponds to that of the folding channel (36) and two storage rollers (44, 45) arranged outside the packing belts (42, 43) and each carrying a web (46, 47) of a strip-like packaging material, for feeding packaging material into the packing channel (41) along one of the packing belts (42;
