| Construction: |
The Griffin Company's construction insures absolute rigidity
in the frame and correct bed movement. Construction is of 2"
x 4" x .180" and 2" x 2" x .180" heavy-wall
rectangular steel tubing for the frame with 8 to 10 2" x
2" x .180" heavy-wall steel tubular cross members.
Solid steel tie-bars connect the frames and hold the adjustable
bed wheels. All exposed steel parts are cadmium plated to prevent
rusting. The press is painted with the best acrylic enamel epoxy
paint for a very durable hard finish. |
| Drive: |
The drive is operated by a single chain reduction of 7 to
1. The chain is nickel-plated to prevent rusting. The bottom
roller is 4-1/2" solid steel turning on heavy-duty, self-aligning
ball bearings that are pre-lubed, sealed and require no maintenance.
A positive key system from the sprocket to the roller prevents
slippage. |
| Pressure System: |
The pressure system is a double lobed concentric cam with
grease fittings in all moving parts. The unit is of very strong
construction and is extremely durable. |
| Bed: |
The bed is of 2-1/2" laminated cherry hardwood. Cherry
wood is the best hardwood for lithography press beds. Under a
variety of atmospheres, it will maintain its dimensional stability.
