Refurbished Machines | CarnaudMetalbox Engineering

		Refurbish your 314 presses and take advantage of the latest Year 2000 modifications including pneumatic buttons on the feed table top plate, pneumatic feed bars instead of springs for increased sheet control. Electrical control system upgraded from relay control to PLC control providing improved timing of sub-assemblies, can also provide greater operator interface controls as well as a platform for greater process control and monitoring.

		The move from a chain and sprocket drive to a timing belt drive has provided noise and cost reductions. Lower maintenance costs have also been achieved. Changes from the existing brass auxiliary feed bars to ones manufactured from Marblon 105 has reduced feed bar wear and also does not mark the sheets being fed.

		Due to the increasing difficulty in sourcing parts for the original Lincoln Lube system the oil and grease system has been upgraded to an Interlube system. Providing the advantages of a lower pressure system incorporating the use of nylon piping over existing steel pipes. Other advantages include the greater adjustability and flexibility of the unit combined with cost savings and availability of spare parts.

		The move from the existing Airflex clutch and brake system to the newer Taylor clutch and brake system has provided the advantage of the new system being housed in a single unit freeing up space on the machine in comparison to the existing two housing unit.

		The move to the Taylor clutch and brake unit has necessitated a modification to the crank, due to the Taylor unit needing a tapered fitting over the existing parallel and key system.

		Within the Curler gearbox upgrades the gear type remains the same but the existing gear is modified in height and adjusting spacers are fitted. This new assembly requires new spindle and curler wheels, and also incorporates a quick release friction joint bush for the curler wheels.

		Further Press upgrades have been carried out in the gearbox with the introduction of spiral cut bevel gears in place of the existing straight cut bevel gears. The plain thrust bearing is replaced with a needle thrust bearing due to the higher thrust loads experienced, due to the action of the spiral gears pulling themselves together increasing the forces experienced above those found with straight cut gears which push themselves apart. The benefits of which are reduced wear and potentially reduced vibration. While these improvements cannot be classified as true anti-backlash gears the new set up does provide greater scope for adjustment to reduce backlash.
