Abstract: A deposition device includes: a cooling unit that cools workpieces; a rotating table main body that rotates around a vertical axis, this rotating table main body having a cooling unit placement portion on which the cooling unit is placed and workpiece placement portions which are arranged so as to surround the periphery of the cooling unit placement portion and on which the workpieces are placed respectively; a lifting mechanism that lifts and lowers the cooling unit, inside the space, between a first position in which the cooling unit is placed on the rotating table main body and a second position in which the cooling unit is spaced upward from the rotating table main body and faces side surfaces of the workpieces placed on the workpiece placement portions; and refrigerant piping attached to the chamber and detachably connected to the cooling unit to supply the refrigerant to the cooling unit.
Abstract: A coating film transfer tool may include a supply reel, a transfer tape, a transfer head, a winding reel, and a power transmitting mechanism. The tool may include a base member having the transfer head and a rotation restraining portion capable of directly restraining rotation of the supply reel. The base member may be rotatably supported between the transfer head and the rotation restraining portion by a base member supporting shaft. The tool may include a resilient restoring mechanism interposed between the base member and the housing. The base member may rotate and restraint of rotation of the supply reel is released when the transfer head is pressed against a transferred surface, and the base member is restored to an original position by the resilient restoring mechanism to restrain rotation of the supply reel when pressing of the transfer head is released.
Abstract: A coating machine component, e.g., a bell plate for a rotary atomizer, and corresponding production methods are disclosed.

Abstract: The device for cooling an adhesive applied to a surface of bag bodies includes a transfer conveyor and a cooling conveyor. The transfer conveyor conveys the bag bodies at a transfer speed to the cooling conveyor, and the cooling conveyor conveys the bag bodies taken over from the transfer conveyor at a cooling conveyor speed. The transfer speed is higher than the cooling conveyor speed, which is why the bag bodies are arranged overlapping each other on the cooling conveyor. Due to this higher packing density, there is achieved a long dwell time of the bag bodies in the cooling conveyor at simultaneously a high flow-rate of bag bodies through the device.
