Historically, the Model 8H Berkel slicer ended up substituting model 20 and models 5-7. Yet, it shows some analogies with the previous versions : in fact also in this flywheel slicer the slicing synchronism is similar to models 5-7. Yet, in Berkel slicer model 8H the parts were improved and optimized, at the point that the company decided to use them for the entire following production ‘till the 60s. In Berkel Model 8H with pedestal we shift from the worm screw with ribbed clamp comb to the conical screw. The machine comb doubles the contact surface and it’s no longer assembled onto the fixing clamp, but on a telescope scrolling headframe. Furthermore, it is inserted in the worm screw at a very high coupling charge. All this – together with the conical coupling – compensates the comb wear and allows to obtain the best efficiency and life length of such professional slicer. In Berkel Model 8H the clamp is inserted and blocked inside a pin poking out on a headframe. Also, the worm screw and the headframe are covered with a shaped carter, unlike the previous models in which they were immediately visible.
It’s about a closed and smooth flywheel slicer. The flywheel operates the gears assembly placed at the base. Such gears generate in turn both the blade movement – by means of a chain – and the scroll carriage – through two connecting rods. Close to the blade side, the carriage scrolls inside a pivot covered by a round protective carter. On the opposite side is instead a squared bar with wheel and a bearing.
Flywheel slicer model 8H unlike models 8H-21, first shows its gears assembly scrolling interlocked inside a squared painted bar. Also, with this design flywheel slicer, the two scrolling guides are supported by four little columns, two for each side, fixed to the base. Moreover on the machine base is a graduated knob for the thickness regulation of the slice which operates a peck-shaped lever in axle to the toothed wheel, placed in turn on the scroll carriage. Rotating the lever, the wheel will convey the movement to the worm screw where the telescope comb headframe is situated, which is hooked to the clamp thus generating the slicing movement. The machine is a manual flywheel slicer and it is so provided with a lever connected to the toothed wheel. Once hand operated in the two directions it will move the clamp right or left to the desired position. The hub supporting the blade of this manual slicer is fixed inside the machine shoulder, which – by its external side – is flattened performing a winged-shaped bow. This will allow the extension of the machine tray so to have more working space on using the flywheel slicer.
Finally, the model in question is a slicer with a closed sharpener covered by a painted crown. A lever will act on the cam which will move the two stones for sharpening.
