Abstract: There is described a vacuum transfer element for transferring a tubular label having a first axis (A) form a first to a second position, comprising a first surface which may reciprocate along a second axis (E) parallel to first axis (A), comprises a plurality of ports and is adapted to cooperate with an outer side, opposite to first axis (A), of said tubular label; first ports are selectively connectable to a vacuum source to establish a vacuum suction action on outer side, at least when first surface moves from first to second position; surface is angularly fixed relative to said second axis (E); first surface is angularly fixed relative to second axis (E).

Abstract: A machine for cutting and moistening plastic tubes, and presenting: a reel about which the tube is wound; a feed device for feeding the tube in a given direction; a cutting device for cutting the tube to define a portion; and a dispensing device for dispensing adhesive on to an end of the portion. The machine also presents a gripping device for gripping the portion during cutting, and for conveying the portion to the dispensing device; and a detecting device which, following dispensing of the adhesive, detects the presence of the operator's hand gripping the portion, and de-activates the gripping device to release the portion into the operator's hand.

Abstract: The invention concerns a haemodialyzer of the type comprising a semipermeable flattened tubular membrane wound in spiral configuration from one end with an interposed insert around a mandrel member, means for connecting the interior of said membrane at its ends to conduits for the admission and discharge of blood, the assembly being housed in a casing in which said mandrel member comprises at least two similar elongated elements which are connected together.
