Abstract: Scraping apparatus for the paper industry, of the type which consists of a scraping blade (l), a support (s) for the scraping blade (l) with a pivot swivel pin (e) with respect to a tray (4), said tray being supported (4) on the frame (b) of the apparatus, characterized because magnetic means are used to exert magnetic forces between the tray (4) or from the fixed element to it and the frame (b), and there are means of action on said magnetic means to activate/deactivate the magnetic forces between the tray (4) and the frame (b). The magnetic means consist of at least one zone (z) of ferromagnetic material and several permanent magnets or electromagnets (1) placed on the tray (4)-frame (b) in a conjugate/corresponding manner.

Abstract: Doctor blade for the paper industry, comprising a scraping plate (1) and holding means (p) for the scraping plate which in turn are held by a frame (a) the ends of which are securely fastened (2) by two fastening points (pf) to a stationary structure (f), characterized in that it comprises: a) mechanical means for adjustable fastening (3) between at least one end (2) of the frame and the stationary structure (f) in such a way that the distance (d) between the two fastening points (pf) can be varied by the user; and b) means for incorporating an additional mass (5) in adjustable quantities.

Abstract: Creping and cutting procedure and equipment, for paper manufacture which consists of a creping doctor (1) carrying a blade (2) which carries out the creping; a corbel (12) which can pivot on a pivot shaft (5) in the geometrical centre of which the creping blade (2) works; primary means of actuation (3) which through the corbel (12) cause the rotation of the creping doctor (1) on a pivot shaft (4); and secondary means of actuation of variation of angle (6) which act on the corbel (12) and cause its rotation on a pivot shaft (5); in such a way that it is possible, with only two doctors (1), (7) to carry out the manoeuvres of creping, blade changing, cutting and cleaning.
