Claim 1
Independent Claim
158 words
A product conveying wheel, the wheel (1) comprising a frame (2); at least one manipulating unit (5) fitted to said frame (2) and in turn comprising at least one movable manipulating element (40); and control means (43) for controlling said manipulating element (40); characterized in that said control means (43) comprise, for each said unit (5), a rotary control shaft (44), and at least one cam (45, 46) fitted to the control shaft (44) and connected to the manipulating element (40); each unit (5) comprising a casing (17) housing the respective control shaft (44) and supporting the manipulating element (40); first removable connecting means (27) being provided for removably connecting said casing (17) to said frame (2); an operating shaft (10) being fitted to said frame (2) and rotating about its own axis (8) in relation to the frame (2); and second removable connecting means (53) being provided for angularly connecting the operating (10) and control (44) shafts.
Claim 2
Dependent Claim
158 words
A product conveying wheel, the wheel (1) comprising a frame (2); at least one manipulating unit (5) fitted to said frame (2) and in turn comprising at least one movable manipulating element (40); and control means (43) for controlling said manipulating element (40); characterized in that said control means (43) comprise, for each said unit (5), a rotary control shaft (44), and at least one cam (45, 46) fitted to the control shaft (44) and connected to the manipulating element (40); each unit (5) comprising a casing (17) housing the respective control shaft (44) and supporting the manipulating element (40); first removable connecting means (27) being provided for removably connecting said casing (17) to said frame (2); an operating shaft (10) being fitted to said frame (2) and rotating about its own axis (8) in relation to the frame (2); and second removable connecting means (53) being provided for angularly connecting the operating (10) and control (44) shafts.
Claim 3
Dependent Claim
