Abstract:
An installation (26) for thermally conditioning thermoplastic preforms (14) that are intended to be formed, the installation (26) including:—a thermal-conditioning zone (40) divided vertically into a heating first part (42) which is intended to house a body (16) of the preform (14) and a cooling second part (44) which is intended to house a neck (20) of the preform (14);—a device (62) for cooling a portion of the preform (14) by producing a stream of gas passing through the thermal-conditioning zone (40); characterized in that the cooling device (62) produces a blade (63) of gas blown with laminar flow through an axial outlet slit (72).
Abstract:
A molding unit (10) for forming a container made of thermoplastic material, includes:—a mold bottom (16) that is movable between a low position, an intermediate boxing position and a high position;—a carriage (24) that supports the mold bottom (16) and is mounted in a movable manner in a fixed holder (26);—actuation elements for moving the carriage (24) into its intermediate boxing position;—the actuation elements including a cylinder (32) that houses a piston (98) liable to push the mold bottom (16) through a boxing travel; characterized in that the mold bottom (16) is supported in a fixed manner by the carriage (24), the cylinder (32) being fixed with respect to the fixed holder (26). A method for employing the molding unit is also described.
Abstract:
The present invention relates to the forming of a container by folding a cardboard sheet with at least vertical flaps, using a forming device and a forming method. Such a device comprises an upstream conveyor driving said cardboard sheet in a direction of travel, a downstream conveyor, means for folding the vertical flaps, said folding means being situated symmetrically about said upstream conveyor, and is characterized in that, on each side, said folding means comprise a pair of downstream and upstream pushers forming a gripper, said pushers being actuated jointly from an open position toward a closed position of folding said corresponding vertical flaps, a support for each gripper, said support being mobile in said direction of travel.
Abstract:
Conveyor for transporting articles such as a chain conveyor that can be changed between a stretched configuration and a compact configuration, the chain being formed from a plurality of articulated links. Each link includes a trolley provided with lateral guide mechanism cooperating with a track defining a predetermined trajectory, a support carrying a nozzle for the releasable attachment of an article, the support mounted rotatably with respect to the trolley between a straight position corresponding to the deployed configuration of the chain, and an oblique position, corresponding to the compact position of the chain and in which the support is inclined with respect to the straight position; and an actuator coupled to the support, capable of driving the support in rotation from its straight position to its oblique position, and reciprocally.
