Abstract
A machine for treating fabrics, comprises--in combination with a wall agat which the fabric is directed in order to strike against the wall and undergo the action thereof--: a duct for the dragging of the fabric; means to feed the fabric to said duct; means to convey a dragging air stream towards the outlet of said duct for the dragging of the fabric, in order to project it pneumatically against said wall, which is grid shaped; and possible means for pneumatic support.
Claims10
A device for treating textile materials comprising:
- a housing defining a working space;
- a grid wall defining openings through which air may pass, said grid wall being connected to said wall;
- a venturi injector having an inner conduit defining a central suction area and an outer conduit surrounding said inner conduit, said venturi injector being positioned within said housing having jet opening directed at said grid wall substantially perpendicular thereto;
- pneumatic pump means having a suction inlet for drawing air into said pump means and a discharge opening for directing air under pressure;
- and, a conduit connecting said pneumatic pump means discharge with said outer conduit of said venturi injector, textile material fed into said central suction inner conduit being dragged by air from said outer conduit and being transported with an air stream into said grid wall, the air stream continuing to flow through said grid and said textile material striking said grid.
An apparatus for washing, breaking and fulling of fabrics, comprising:
- a housing defining an interior work space;
- a grid wall positioned within said housing, said grid wall forming opening through which air may pass;
- pneumatic venturi means positioned within said housing for dragging fabric from an inlet to an outlet, said venturi means including an inner central suction conduit and an outer high pressure air conductor;
- means to feed said fabric to an inlet of said venturi means;
- and, direction means for directing said dragged fabric and an air stream provided in said venturi means towards said grid wall so said air stream continues to flow through said grid and said fabric strikes said grid wall.
