Title: Device for forming pieces of cheese
Inventor: DOHLE GUENTER
IPC: A01J25/11
Filed: 1987-01-23
Granted: 1988-04-14
Abstract: In a device for forming pieces of cheese from mould tubes (1) adapted to the cross-section of the pieces of cheese and filled with curd, there are forming chambers (15) below and aligned with these mould tubes, for receiving the ribbons of curd to be cut off with a parting slide (13). These forming chambers are closed at the bottom by a supporting slide (19), which can be retracted to eject the formed pieces of cheese from the forming chambers into the mould troughs (23) of a mould unit. The forming chambers (15) are formed by a respective forming jacket (16) and a lowering sleeve (17) that can slide up and down on the outer surface of this jacket. The supporting slide (19) can move with the lowering sleeve, so as to ensure with these thus divided forming chambers rapid and undamaged parting of the cut-off pieces of cheese from the parting slide (13) and from the forming chambers. <IMAGE>
