The present invention relates to a self-propelled shredder device (1) for shredding dry or wet green waste material, including leaves, woody branches, palm tree prunings, olive tree prunings, bamboo prunings and others. The device (1) comprises a frame (10) supporting a plurality of rotating movement members (8A, 8B) whose rotation causes the advancement on the ground of said device (1). The device (1) further comprises drive means (16A, 16B) connected to said rotating members (8A, 8B) to rotate them. The device includes a shredding chamber (15) in which shredding means (30) of the waste material are housed. This chamber communicates with a loading hopper (13) for loading the material to be shredded and with a discharge conduit (14) for discharging the material. The device is provided with a thermal engine (MT) supported by said frame (10) and mechanically connected to said shredding means (30) for driving them and shredding the material. According to the invention, the drive means (16A, 16B) which cause the advancement on the ground are of an electrical type.

The present invention relates to a method for drying a flexographic plate (5) previously subjected to washing with a water-based or solvent-based liquid. The method according to the invention involves providing a support member (10) made of a thermo-conductive material, wherein said support member (10) comprises at least a first main surface (10A) adapted to allow the support of said plate (5) to be dried. The method involves positioning the plate (5) to be dried on the support element (10) so that a base face (5A) of the plate rests on said first main surface (10A). The method further provides the step of heating, by means of thermal energy generating means (100), said support element (10) to a preestablished temperature so that the thermal energy supplied to said support element (10) is transferred by conduction to said plate (5) resting on said support element (10) so as to cause evaporation of residual liquid contained in said plate. The invention also relates to an apparatus for carrying out a drying method according to the invention.

The present invention relates to a method for developing a flexographic plate (5), wherein said developing method comprises the step of providing washing means for washing the plate (5) by means of mechanical brushes (17) and a water-based liquid or a solvent-based liquid. The method further comprises the step of providing heating means for heating said face to be developed (5B) of the plate (5). The method according to the invention further comprises the step of heating, by means of said heating means, the face to be developed (5B) of the plate (5) to a predetermined temperature and the step of washing the plate (5) by means of said washing means (10) when the face to be developed (5B) of the plate 5 has reached said predetermined temperature.

A slide-in clamping device (100) for removably connecting a first electrical terminal of a withdrawable low-voltage circuit breaker to a corresponding second electrical terminal of a respective stationary base in a withdrawable low-voltage circuit breaker unit comprises at least one pair of first clamping fingers (131) facing each other and at least partially laterally delimiting a first clamping seat (110) for one of said first and second electrical terminals, the first clamping seat (110) comprising a respective slide-in opening (111); at least one pair of second clamping fingers (132) facing each other and at least partially laterally delimiting a second clamping seat (120) for the other of said first and second electrical terminals, the second clamping seat (120) comprising a respective slide-in opening (121) facing oppositely relative to the slide-in opening (111) of the first clamping seat (110); bias elastic means (140) acting on said at least one pair of first clamping fingers (131) and said at least one pair of second clamping fingers (132) so as to urge the clamping fingers (131, 132) of each pair towards each other in a clamping direction (Y-Y) substantially perpendicular to respective slide-in directions (X1-X1) of said first clamping seat (110) and said second clamping seat (120). In the clamping device (100) at least one displaceable spacer assembly (170) is provided having a displaceable spacer member (171), wherein the displaceable spacer member (171) is displaceable between an active position, in which the displaceable spacer member (171) contacts the first clamping fingers (131) of the at least one pair of first clamping fingers or the second clamping fingers (132) of the at least one pair of second clamping fingers urging them away from each other in the clamping direction (Y-Y), and an inactive position, in which the displaceable spacer member (171) does not apply any force to said first clamping fingers (131) or said second clamping fingers (132).A withdrawable low-voltage circuit breaker unit comprising the slide-in clamping device (100) is also disclosed.
