A thermal bonding appliance (10) combined with a calendering, smoothing and/or embossing roller pressing appliance (20) and intended for the treatment of absorbent pads on articles of hygiene consists of a pressure band (A) which rotates endlessly via a heating cylinder (11) and rollers (17, 16, 15, 14, 13, 12) back to the heating cylinder (11) and which partially loops adjustably around the circumference of the heating cylinder, the absorbent pads, individually lying freely or joined in sheet form and each covered on one side and/or on both sides with a covering sheet, being guided between the looped-round surface of the heating cylinder (11) and the pressure band (A). For the perfect introduction and fault-free run-through of the absorbent pads to be bonded, even at very high working speeds, there is a laying-down device (40) for an endlessly rotating filamentary material (44), preferably a wire rope, laid at a mutual distance over the sheet width, the absorbent pads (F, F') predominantly being guided between the wire-rope laying-down device (40) and the pressure band (A). A press roller (21) of the calendering, smoothing and embossing roller pressing appliance (20) so interacts with the heating cylinder (11) outside the looped-round region of the pressure band that the heating cylinder (11) is additionally a calendering roller. |
