摘要:
A mixer machine (1) comprising a mixing chamber (1a), housing at least two counter-rotating rotors, into which materials to be mixed are pre-established in loaded proportions, said chamber having discharging means (1b) of the mixture at the bottom and a loading throat (1c) at the top into which a plugging and pressing plunger (10) runs, a system of hydraulic pistons (11, 12), lifting said plunger (10) off the loading throat (1c) for loading the materials to be mixed and lowering back the plunger (10) into said throat (1c) to prevent extruding of the mixture and to bear on the mixture, has the thrust block (16) connected to and moved up and down by said hydraulic pistons, defining at the bottom a chamber of a pneumatic cylinder, whose piston (17) is connected to the stem (15) of said plunger (10), sealingly passing through a hole of said thrust plate (16). A pneumatic circuit controls the pressing and/or the floating of said plunger (10) on the mixture and resiliently absorbs thrusts transmitted to the plunger (10) by the materials being mixed.

In a method and apparatus for producing mechanically compacted non-woven fabric, a web of non-compacted fibres (10) is supplied by means of a conveyor belt (12) to a calender (14) having a pair of heated compacting rollers (16). The web (10) is supplied to the compacting rollers (16) downwardly from above.
摘要:
A device is described for enabling and disabling the needle bars (2) and the piercer bars (3) according to a predetermined program in an embroidery machine, comprising means or hooks (4) suitable to connect said bars (2,3) to an oscillating drive bar (1). Such hooks (4) are operated by a single actuating member (16) which connects the oscillating drive bar (1) either to the needle bars (2) or to the piercer bars (3), and selecting levers (26) are provided suitable to connect to the oscillating drive bar (1) either all of the bars (2,3) or some of them which, according to said program, have not been connected to the drive bar (1) by said actuating member (16).
