Abstract:
A feeding device for a press comprising: a first belt (2), movable in advancement along a conveying direction (X) and passing through a press (11, 12); depositing means (3), predisposed for spreading in a layer an amount (L) of loose material (L) on a movable plane. The device comprises a second belt (4), on which the depositing means (3) operate, located upstream of the first belt (2), which is movable along the conveying direction (X) and is substantially aligned and contiguous to the first belt (2). The first belt (2) and second belt (4) are movable independently of one another.
Abstract:
A control method for detecting the operating status of the nozzles of an ink-jet printhead, comprising the following steps: detecting an inlet pressure and an outlet pressure in a feeding channel (5) of the nozzles (6) in a closing condition of all the nozzles (6); detecting a reference pressure differential between the inlet pressure and the outlet pressure; opening each nozzle (6) in sequence and separately from the others; detecting the pressure differential between the inlet pressure and the outlet pressure in an opening condition of a single nozzle (6); comparing the detected differential pressure with the reference pressure differential.

Abstract:
A kiln for slabs made of a ceramic material, comprises a support structure (2) defining a longitudinal conduit (3) developing along a prevalent development direction (A), a firing station (12) internal of the conduit (3) in which a slab (4) remains at a predetermined firing temperature for a predetermined period of time and a preliminary cooling station (13) internal of the conduit (3) and operatively located downstream of the firing station (12). A plurality of rollers (5) located side-by-side and parallel along the prevalent development direction (A) is connected to the support structure (2) and defines a sliding surface (B) of the slab (4), movement means (6) of the rollers enable transport of the slab (4) from the firing station (12) to the preliminary cooling station (13). The rollers (5) arranged in the preliminary cooling station (13) each exhibit an end (5a) which is connected to the drive means (6) via an elastic joint (7) and the preliminary cooling station (13) further exhibits a succession of electric heating resistance elements arranged along the prevalent development direction (A) below the rollers (5).
Abstract:

Abstract:
An actuator device, particularly for ink-jet heads, comprising: two or more electromagnetic actuators or solenoids (S), each comprising a ferromagnetic core (2), and a conductive winding or coil (4), arranged concentrically to the ferromagnetic core (2); a containment body (5), which encloses the electromagnetic actuators (S); an insulator element (1) for each solenoid (S). Each insulator element (1) is made of a magnetic material and is disposed at least partially in proximity of a respective solenoid (S).
Abstract:
A decorating apparatus for decorating objects (5), in the form of slabs or bars, comprises an arrangement of decorating machines (10) including one or more decorating machines (2A, 2B, 2C), each decorating machine (2A, 2B, 2C) being provided with a decorating head (4 A, 4B, 4C) and a conveying device (3 A, 3B, 3C) including support surface means (11) suitable for supporting and conveying the objects (5) to be decorated below the decorating head (4) along an advancing direction (F); the decorating apparatus further comprises an auxiliary advancing element (16) suitable for receiving and supporting the objects (5) to be decorated, the auxiliary advancing clement ( 16) being draggable by the support surface means (11) along the advancing direction (F) through the arrangement of decorating machines (10).
Abstract:
The invention relates to an apparatus for sorting objects, comprising: gripping means (5) for operating a gripping of single objects conveyed on a conveyor line (1) located upstream, transferring the objects along a trajectory and depositing the objects (10) at predetermined temporary depositing points along the trajectory on a predisposed support structure (2); transfer means for removing on command the objects (10) from the support structure in order to transfer the objects to a station downstream. The gripping means (5) transfer the objects (10) along a trajectory which develops parallel to the support structure (2). Also provided are means for predefining the predetermined points of the trajectory and for enabling identification for a following collection.
