This invention concerns a process for monitoring the degree of wear of a compression worm (8) which conveys a plasticized material, in particular, plastic, against an element that exerts a resistance and is located in a worm housing (4). To this effect, the pressure of the material conveyed is measured at two points disposed at intervals along the direction of travel. These two points are situated at both sides of a resistance body (12) towards which the compression worm (8) conveys. The difference between the two pressures measured is used to display the degree of wear of the worm (5) and its housing. A device for that purpose has an opening (18) which penetrates the wall (20) of the housing (4) of the worm (5) in the region of its thread or in a region immediately adjacent thereto. An additional opening (19) penetrates the wall of this housing (4); both openings (18, 19) are disposed axially at a distance from each other. A pressure sensor (22, 23) is linked to each opening (18, 19).
L'invention concerne un procédé pour la surveillance du degré d'usure d'une vis de compression (8) transportant un matériau plastifié, en particulier du plastique, contre un élément exerçant une résistance, cette vis (8) étant placée dans une enveloppe (4). On mesure à cet effet la pression du matériau transporté à deux emplacements situés à distance l'un de l'autre dans le sens du transport. Ces deux emplacements se situent de chaque côté d'un corps exerçant une résistance (12) contre lequel la vis d'étanchéité (8) transporte le matériau. La différence entre les deux pressions mesurées est utilisée pour l'affichage du degré d'usure de la vis (5) ou de son enveloppe. Un dispositif de surveillance approprié selon l'invention comporte une ouverture (18) pénétrant dans la paroi (20) de l'enveloppe (4) de la vis (5), dans la zone de ses spires ou dans une zone à proximité immédiate de celles-ci. Une autre ouverture (19) traverse la paroi de cette enveloppe (4), les deux ouvertures étant disposées à distance axiale l'une de l'autre. Un capteur de pression (22, 23) est relié à chacune des deux ouvertures (18, 19).
