    摘要: Apparatus for manufacturing cylindrical tubes from paper or similar fibrous materials. A layer of plastics material which becomes tacky when heated provided on a paper web is heated through the paper web then pressed against a plastics foil web with one edge of the plastics foil web extending beyond the corresponding edge of the paper web. The joined webs are wound helically onto a mandril with the extended edge of the plastics foil web overlapping a corresponding opposite second edge of the plastics foil web. A string of molten adhesive is applied along the extended edge on the mandril. The mandril is cooled to maintain the foil layer nearest the mandril below its melting temperature.

    摘要: The present invention relates to a method of manufacturing from paper and other similar fibrous materials cylindrical tubes comprising an inner, dense, liquid-tight plastics foil layer, in which method at least one paper web and a plastics foil web are wound helically together on a rotating mandril with the plastics foil web located against the forming surface of the mandril, and in which the plastics foil web is bonded to the paper web by means of an adhesive. The invention also relates to an apparatus for carrying out the method.

    摘要: An apparatus for taking a sample of a toxic and/or radioactive substance byntroducing such substance into a sample vessel. The apparatus includes a rotatable cylinder containing a recess for receiving a sample vessel. A drive shaft is connected to the cylinder for imparting rotary and axial movements to the cylinder for moving the recess of the cylinder between first and second positions. A needle head filling system is arranged above the cylinder at the first position for filling a sample vessel with toxic and/or radioactive substances. The cylinder is lifted by the shaft for engagement with the needle head filling system when being filled and lowered by the shaft after being filled. An inlet and outlet conduit is provided having one end for receiving from and discharging into the recess of the cylinder a sample vessel, the one end being located above the cylinder at the second position. A stripper is located between the cylinder and the needle head filling system for disengaging the sample vessel from the needle head filling system when the cylinder is lowered by the shaft after being filled.
