The Mosstype Optical mounting system, first introduced in 1969 has through its recognized performance grown to include fourteen models with specialized sizes and mounting features to suit most flexographic printing applications.
The machines while low in cost include many automatic features to simplify the operation and that enable operators to produce accurate work, and also substantially more mounting production per shift.
The Mounter-proofers combine a very accurate optical viewing system, a rigid machine structure, and low voltage electrical controls that together have been proven through years of maintenance free operation.
The optical viewer is partially mirrored to reflect half of the light striking the surface and to allow half to transmit through. The view of the proof is reflected and appears superimposed on the plate, which is seen through the glass. The plate is registered by moving it to coincide with the reflected view of the proof. A magnifier fitted onto the viewer assembly is used for close work. Depending on the task, plates can be registered using either register marks or by matching an image on the plate to an image of the proof. Having this flexibility is a very productive feature.
The gearing system is designed to run with zero backlash, however, the gears have an indefinitely long service and baring damage, never require replacement.
On large repeat machines the gears are counterbalanced for uniform contact pressure and better proofing over the full range of diameters.
Gears are available to match any press system and optional multiple gearing systems can be used.
The electrical control system automatically moves the plate cylinder to the load, mount or proof position and reliably maintains close repeatability of the settings.
At the Proof position the vertical travel of the plate cylinder is converted to display the actual impression squeeze for all diameters.
