Beschreibung
Zusammenfassung:	Screw press, preferably for removing liquid from a material to be conveyed, comprising a screw shaft (1) complete with a helical conveying flight (2) mounted on the screw shaft (1) and a housing shell (3) surrounding it, where a transport channel (4) is formed for the material to be conveyed between the screw shaft (1), the conveying flight (2), and the housing shell (3). In order to prevent conveyed material components from adhering to the screw shaft (1), and thus uneven filling of the transport channel (4), the invention provides for the screw shaft (1) to have a surface profile (5), at least in one section of the transport channel (4). Une presse à vis, de préférence pour retirer un liquide dun matériau à transporter, comportant un arbre à vis (1) doté dune tige de transport hélicoïdale (2) fixée sur larbre à vis (1) et dune coquille de boîtier (3) qui lentoure, un canal de transport (4) étant formé pour le matériau à transporter entre larbre à vis (1), la tige de transport hélicoïdale (2) et la coquille de boîtier (3). Afin dempêcher les composants de matière dadhérer à larbre à vis (1), et déviter ainsi un remplissage inégal du canal de transport (4), linvention prévoit que larbre à vis (1) soit doté dun profil de surface (5) dans au moins une section du canal de transport (4).
