Claims

1) Reinforcing machine for positioning angular reinforcements (Rs), comprising: a support plane (2) for an object (P); at least one magazine (3), arranged to contain at least one reinforcement profile (R); characterised by the fact that it comprises: cutting means (31), arranged to cut the reinforcement profile (R) in correspondence with a cutting plane (C), so as to separate a reinforcement (Rs) from the reinforcement profile (R); feed means (32), arranged to translate the reinforcement profile (R) in advance along a direction transversal to the cutting plane; a positioner (33), configured to pick up a reinforcement (Rs) and to position the reinforcement (Rs) in contact with or in proximity to the object (P). 2) Reinforcing machine according to claim 1, wherein the cutting means (31) are positioned so that the cutting plane (C) is located at one end of the magazine (3). 3) Reinforcing machine according to one of the preceding claims, wherein the feed means (32) can be actuated to move the reinforcing profile (R) forward by an adjustable stroke, so as to make a portion of the reinforcing profile (R) of the desired height protrude beyond the cutting plane (C). 4) Packaging machine according to claim 3, wherein: said advancement means (32) are made by said cutting means (31), comprising a blade (31a) movable between a forward position, in which it is arranged below the magazine (3), and a backward position, in which it is not arranged below the magazine (3); in the forward position of the blade (31a), the profile (Rs) rests on the blade (31a); 71.S0721.12.IT.197 Ing. Giovanni Casadei (Register no. 1195 B) in the backward position of the blade (31a), the reinforcement profile (R) is free to descend by gravity by a pre-established distance. 5) Machine according to one of the previous claims, wherein the positioner (33) is placed downstream of the cutting plane (C) with respect to the direction of advancement of the reinforcement profile (R). 6) Machine according to one of the preceding claims, wherein the positioner (33) comprises a cursor (34), movable along a trajectory which passes close to the cutting plane (C), downstream of the latter with respect to the direction of advancement of the reinforcement profile (R), so that the cursor (34) is able to come into contact with a reinforcement (Rs). 7) Reinforcing machine, according to one of the preceding claims, comprising four operating units, each of which comprises: a magazine (3); cutting means (31); feeding means (32); a positioner (33); according to one of the preceding claims, wherein said operating units are arranged substantially at the vertices of a quadrilateral. 8) Reinforcing machine according to claim 7, wherein said operating units are movable on at least one plane, to allow the mutual distances between the operating units themselves to be adjusted. 9) Packaging machine for ceramic slabs or tiles, comprising: a transport plane (21), movable along a transport direction (A); a closing device (5), arranged to fold into a closing configuration a package (100) comprising four foldable sides so as to overlap at least partially with respective sides of the object (P); a reinforcing machine according to one of the previous claims, arranged upstream of the closing device (5) with respect to the direction of advancement along the transport direction (A); in which the support plane (2) of the reinforcing machine is aligned and coplanar with said transport plane (21), or is defined by a portion of said transport plane (21). 10) Method for packaging objects (P), comprising the following steps: arranging a package (100) in a flat configuration, which comprises four sides that can be folded so as to overlap at least partially with respective sides of an object (P), on a support surface (2) or on a transport surface (21); arranging an object (P) on the package (100); cutting at least one reinforcement (Rs) from a reinforcement profile (R); positioning the reinforcement (Rs) above the package (100), in contact with or near the object (P); closing the package (100), so that the reinforcement (Rs) is inside the package (100) in contact with the product (P). 11) Method according to claim 10, wherein the step of cutting at least one reinforcement (Rs) from a reinforcement profile (R) comprising the steps: cutting four reinforcements (Rs) from respective reinforcement profiles (Rs) or from the same reinforcement profile (R); positioning each reinforcement (Rs) above the package (100), in proximity to or in contact with the object (P); closing the package (100), so that the reinforcements (Rs) are inside the package (100) in contact with the object (P).
