Abstract: The invention relates to a tampon (10), to the essentially cylindrical circumferential surface of which a liquid-permeable, thermoplastic material is fastened, with the application of pressure and heat. The dome-like constriction (10b) at the introduction end (10a) and the withdrawal end (10c) of the tampon (10) remain free of the liquid-permeable, thermoplastic material.

Abstract: Uniform lengths of elastic tape are secured to a continuously advancing mrial web, for example, to make baby diapers. First an intermittently advancing tape is repeatedly gathered, for example, by laying tape sections into a depression of defined dimensions, to relieve the tape sections of any stretching.

The apparatus used for performing these steps has several cooperating rollers of which the first has the depressions in its surface and is rotated intermittently while the second roller is rotated continuously. The spacings between neighboring tape sections bonded to the web preferably have a uniform length.

Abstract: The present invention provides a process and apparatus for the separation of strip sections from a first moving material web, for the subsequent application of these strip sections on discrete areas lying at a distance one behind the other of a likewise moving second material web, wherein the predetermined distance is achieved by moving the separated strip sections apart.
