摘要:
Plant for supplying machines with dyes for the continuous dyeing of textile materials, comprising means for preparing a dyeing bath, the dyeing bath consisting of a mixture of dyeing products, chemicals and/or auxiliary products in aqueous solution, said means comprising an apparatus (12, 13, 14) for the preparation of dyeing solutions in preset strengths starting from said dyeing products, a plurality of tanks (1) for said chemicals and/or auxiliary products to which one or more pumps (6; 10) are associated for the removal of respective products, and an array of conduits for water supply. The outlets of said means are connected to a manifold (26) downstream of which is a dyeing machine (M) to be supplied, and to which manifold (26) means (27) are associated for mixing the products arriving thereat: the means for the preparation of the dyeing bath being associated to a programmable electronic unit (U). (FIG. 2).
摘要:
A plate (1) supports a sample of the material under test, and a clamp or compressor (2; 7; 72) compresses the sample and a multifibre witness or fabric standard (4) on the plate (1). The plate (1) defines a plurality of through holes (12) associated with an injection system (5) for injecting one or more liquids through the holes (12).
摘要:
Apparatus for the controlled withdrawal and delivery of volumetrically metered liquids of a type comprising a support structure able to receive a first series of vessels or bottles which contain substances in a liquid phase, and a second series of vessels or glasses able to receive one or more said substances in preset doses, means being provided for withdrawing and feeding said substances in preset doses and able to withdraw said substances individually from said bottles and discharge them into said glasses, apparatus characterized in that said withdrawal and delivery means comprise a series of single withdrawal and delivery members (7) able to be positioned in correspondence of each of said bottles and resolvably matchable with an actuation and driving head (6).
摘要:
An apparatus for the preparation of mixtures, especially dye solution. The apparatus includes a device for withdrawing a predetermined batch of product at a withdrawal station and for transferring the product to a separate dissolution station (SD). A device is provided for the dissolution of the product in the solvent, disposed in the dissolution station. A programmable electronic device is provided for operating the devices for withdrawal, transfer and dissolution of the product. The device for dissolution includes in a fixed horizontal plate with an annular seal housed in a corresponding channel of the lower surface of the plate making up a tight-sealing element for the mouth of a corresponding cylinder vessel containing the product to be dissolved. The vessel is associated with a vertical operating cylinder for driving the vessel from a lower to an upper position. A doctor blade is provided supported by a vertical shaft which is in a fixed spatial position and goes through a central hole of the plate to be supported by the latter. This vertical shaft is associated to a corresponding driving member for moving the doctor blade. A lump-breaking body is carried by a rod passing through a corresponding hole of the plate. The rod is associated to a corresponding driving member. One or more conduits with valves are provided for the supply of hot or cold water or other solvent into the vessel. An in-line pump is for the withdrawal of the solution from the vessel.
