RPA S.r.l.

An apparatus (1) for finishing a object (3), comprising a supporting member (15) and a mechanical cutting device, wherein the supporting member (15) delimits a through hole (19) which prevents the passage of the object (3) to be cut and allows the passage of the finished object (5) to be obtained, and wherein the mechanical cutting device comprises a first cutting member (9) movable relative to the supporting member (15) between an uncoupled configuration, and a coupled configuration, in which the first cutting member (9) is inserted in the through hole (19), the apparatus (1) being switchable from the uncoupled configuration to the coupled configuration in order to carry out, in use, a cutting operation on the object (3) along a closed line and thereby to obtain the outer annular edge (7), separating the finished object (5) from a piece of scrap (23). A method implementable with the apparatus (1) is also claimed.

A method for obtaining a plurality of individual objects (1), separated from each other, which comprises a pre-cutting step, in which a semi-finished product (2) is cut and a plurality of unfinished objects (9) separated from each other is obtained, a positioning step, in which the unfinished objects (9) are positioned according to a spaced apart arrangement, a centring step in which a main portion (3) of each of the plurality of unfinished objects (9), corresponding to one of the individual objects (1) to be obtained, is centred relative to the reference axis (8) of a respective cutting device by translating, starting from the spaced apart arrangement, at least one of the unfinished objects (9) by a respective correction distance (12) in a plane perpendicular to the reference axis and a cutting step for cutting the plurality of unfinished objects (9) in which each main portion (3) is separated from an annular piece of scrap (13).

A method for making a container which comprises an inner laminating step during which a plastic first sheet (14) is laminated at an inner side (8) of a supporting core (7) of cellulose material, an outer laminating step during which a plastic second sheet (15) is laminated at an outer side (9) of the supporting core (7) and a sealing step during which the first sheet (14) and the second sheet (15) are sealed to each other and the supporting core (7) is completely enclosed between the first sheet (14) and the second sheet (15) to obtain a first part of the container. Moreover, the first part (2) is then fixed to a second part (3) of the container, by fixing one of either the first sheet (14) or the second sheet (15) to a surface layer (19) of the second part (3) which is constituted of a plastic material.

A computer-implemented method for predicting a real strength grade which a known grading device (7) will assign to a real wooden board (2) not yet cut from a log (6), comprising a virtual cutting step of a three-dimensional virtual model (1) of the log (6) to obtain a virtual board (4), an assigning step, during which surface and/or internal characteristics are added to the virtual board (4), a virtual grading step, during which a virtual strength grade which the known grading device (7) would assign to the virtual board (4) is estimated, a predicting step, during which it is assumed that the real strength grade, which the known grading device (7) will assign to the real wooden board (2), corresponds to the virtual strength grade estimated in the virtual grading step.

An apparatus for conveying objects, comprising a guide (2) with linear motors and a carriage (3), which is coupled to the guide (2). The carriage (3) comprises a movement element (4), slidably associated with the guide (2), a supporting element (5), which defines a housing (15) for housing an object and is connected to the movement element (4), and a base body (18) which is fixed to the movement element (4). The movement element (4) comprises at least one wheel (8). The carriage (3) also comprises a lubricating system (42) which is configured to feed, in use, a lubricating liquid (43) to the at least one wheel (8) and which comprises a tank (44) to contain the lubricating liquid (43). The tank (44) is a cavity made in the base body (18) and open at the top.

A thermoforming apparatus (1) for applying a coating film (2) to a support (3) comprising a bottom wall (4) and a lateral wall (5) which define an inner surface (6) and an outer surface (8). The thermoforming apparatus (1) comprises a supporting element (14), defining a housing space (15) for the support (3), and a closing element (16), which are movable between a home position, in which they are spaced apart, and a working position, in which they are coupled. The thermoforming apparatus (1) comprises means for creating a vacuum (19) for causing the coating film (2) to adhere to the inner surface (6), and a movable application element (23) for applying a portion (34) of the coating film (2) to the outer surface (8) at the lateral wall (5).
