For this reason, it is fitted with drop feed and an additional vibrating presser which can be

to make the same, a shorter or a longer stroke than the feed dog, as appropriate.

Thanks to the incorporation of maintenance-freeanti-friction bearings, pad lubrication in the
gear case,

time required for machine care is extremely low.
