The arm 10 carries an admovable between the

The required as the arm sinks. adjustment of the plate 24 may be effected by 11 screw-actuated cam means. Thus the plate may be provided with a tooth engaging in a slot 26 in an adjustable block 27 located in a guiding groove 28 in a cap-piece 29. In this way the thickness of the film of paste taken up by the pasting disc may be regulated as desired while the machine is running.

The opposite end wall of the nozzle maybe formed as a separate removable plate 30 which closes the rear end of thenozzle and also acts as a scraper for removing dried paste from the edge of the disc before it passes into receiving relation with the nozzle. Theplate 30 is located in a groove formed in the closure member 19 and is held in set position by the screw 31. A scraper 42 is pivotally mounted on the gear casing at .43 whereby it may be moved in engagement with the pasting disc (see Figure 1) spring means 44 being provided for holding it normally away from the disc.

The pasting disc 23 and paste feeding drum 16 are driven through gearing or other convenient means at suitable speeds depending on the conditions under which the device is required to operate. For example, the pasting disc may be driven through

gears

32, 33, 34, from the spindle 36 which latter is provided with a bevel gear 3'7 meshing with a bevel 38 on the spindle 39 coupled to the drum spindle 40 by a clutch 41. It will be understood that the teeth of the rotatable feeding drum act to mill the paste which is thereby softened and given a consistency suitable for the purpose in View, and the paste is then forced or pumped into the nozzle by the pressure of the tooth faces.

The feeding drum may, if desired, be made of cylindrical or other desired shape and it will also be understood that the invention may be applied to mechanism adapted for use with ordinary liquid or semi-liquid pastes.
