A special procedure for the

manufacture of the carriage

1. Housing manufacture: The cover, bottom, left pillar, right pillar and

black wall are "rst stamped out from a reel on a CNC stamping machine,
then bent on a CNC bending machine.
2. Manufacture of wheel holders and handle reinforcement:

The wheel holder is "rst cut with shears, bent on a tool (in two stages),
pierced and threaded for wheels. The handle brace is stamped out from a
reel on a CNC stamping tool, then bent on a CNC bending machine and
riveted onto the left pillar.

3. Housing welding: Then all the elements are loaded into a robotic
cell for housing welding and the entire housing is welded before being
transported for varnishing.

Drawer production

Drawer 70 is stamped out from a reel on a CNC stamping machine, then
bent on a CNC bending machine, pressed on a tool and spot welded
using a spot welding device. The drawer is thus ready for coating.

Drawer 160 is stamped out from a reel on a CNC stamping machine,
then bent twice on a CNC bending machine, pressed on a tool and spot
welded using a spot welding device. The drawer is thus ready for coating.

A lifting rod is cut out with a laser on a laser cutting machine, pressed
on a tool, bent on a CNC bending machine and then transported for
coating. After coating, all the elements are ready for the ASSEMBLY of the
carriage, which is carried out on the assembly line.

The assembly includes the following actions:

› Serigraphy of the drawers
› Assembly of the drawers (the lifting rod and guides are riveted to the
drawer and a synthetic lining is inserted)
› Serigraphy of the housing
› Placing the synthetic lining and border onto the carriage cover
› Assembly of the lock and the locking mechanism
› Riveting the guides onto the housing
› Inserting the drawers
› Examining the carriage and inserting the wheels and handles into the
drawer
› Packaging the carriage in Styrofoam using a specialpackaging device
› Final packed products
