Abstract:
This device consists of a pump which delivers ink from a tube of ink to a reservoir device of the apparatus called ink trough, this tube of ink being tightly fitted to a first bore of the pump, and a duct, one end of which is tightly fitted to a second bore of the pump, connecting this latter to the ink trough. It is characterized in that said pump (10) is a membrane pump, controlled by compressed air, and in that said membrane (11) is clamped between two casings (13, 14), the first casing (13), in which are provided the first bore (15) and the second bore (16), providing the circuit for the ink and containing for this purpose a plate (20) which forms the seat for a suction valve (21) and a delivery valve (22), the plate (20) defining with the walls of the casing (13) and the membrane (11) a chamber (29) which, when the pump (10) is primed, will be constantly filled with ink, and the second casing (14) providing the pneumatic circuit and containing for this purpose a piston (35) which is applied against the membrane (11) and made integral therewith. Specially designed with respect to the physical characteristics of the ink used as well as the small quantities to be transferred, this device requires no maintenance or emptying. The tube of ink is screwed to a bore of the pump inside which the ink, sheltered from the air, does not dry, even during long shut-down periods of the cigarette-making machine.
