Apparatus to transport and cool rolled products such as rods, wires, round pieces or similar

Apparatus to transport and cool rolled products (11) able to be arranged downstream of a coil-forming head (12), comprising:

• a plurality of transport rollers (20), at least partly motorized and arranged parallel to each other so as to define a substantially horizontal transport plane on which said rolled products (11) arranged in coils (16) are able to lie,
• ventilation means (22) arranged in correspondence with said transport rollers (20) to blow air towards said rolled products (11) and
• conveyor means to convey towards the lateral edges of said coils (16) a greater quantity of air than that conveyed towards the central zone of said coils (16),
• wherein said conveyor means comprise a plurality of elements (23) arranged at intervals between said transport rollers (20), each of said elements (23) being shaped so as to define transit channels (27) having at least a first transverse section which is greater in correspondence with the ends of said transport rollers (20) and at least a second transverse section which is less in correspondence with the median zone of said transport rollers (20) and said elements consist of intermediate rollers (23) with a variable diameter.

• wherein said ventilation means comprise a plurality of blowers (22), wherein with each of said blowers (22) is associated at least a switch (30) arranged inside an air conveyor conduit (31), located between the corresponding blower (22) and said transport rollers (20) and able to divert the air blown by the blower (22) towards said first greater transverse section,
• wherein two switches (29, 30) are associated with each of said blowers (22), and
• wherein said two switches (29, 30) are connected with each other by means of a pair of gears (35, 36) so that their inclinations are synchronized.
