Installation for producing containers having a wheel for bypassing a coating station

An installation (20) for producing thermoplastic containers (18) comprising:

• a container coating station (34) comprising an input wheel (38) and an output wheel (40), each of said wheels (38, 40) being equipped with gripping elements (39, 41) that are uniformly distributed on its periphery;
• an upstream transfer wheel (42A) that is equipped with gripping elements (44A) that are uniformly distributed on its periphery, the upstream transfer wheel (42A) being positioned to make possible the transfer of containers (18) by synchronized passage when a gripping element (44A) of the upstream transfer wheel carrying a container coincides with a gripping element (39) of the input wheel (38) in an input tangential zone (54A) between the two wheels (42A, 38);
• a downstream transfer wheel (42C) equipped with gripping elements (44C) uniformly distributed on its periphery, the downstream transfer wheel (42C) being positioned to make possible the transfer of containers (18) by synchronized passage when a gripping element (41) of the output wheel (40) carrying a container (18) coincides with a gripping element (44C) of the downstream transfer wheel (42C) in an output tangential zone (54B) between the two wheels (42C, 40);
• further comprising a bypass wheel (42B) equipped with elements (44B) for individual gripping of containers (18) that are uniformly distributed on its periphery, the bypass wheel (42B) being directly tangent with the upstream transfer wheel (42A) in an upstream tangential zone (49A) and the bypass wheel (42B) being directly tangent with the downstream transfer wheel (42C) in a downstream tangential zone (49B), the gripping element (44B) of the bypass wheel being structured for cooperating with the gripping element (44A) of the upstream transfer wheel for receiving the containers and for cooperating with the gripping elements (44C) of the downstream transfer wheel for releasing the containers.
