Title: Method and apparatus for forming elastic elements under tension from a continuous elastic web, particularly for manufacturing sanitary products such as disposable diapers and the like
Inventor: BIANCO CARLO
IPC: A61F13/15
Filed: 1984-10-11
Granted: 1988-08-18
Abstract: @ A supply source (14) of continuous elastic web (13) and a support (11) for the fixing of elastic elements (4) are provided. On the support, which is normally constituted by a rotary drum, there are located at least one clamping element (12) fixed to the support (11) itself and a further clamping element (15) which is movable relative to the fixed element between first and second positions (A,B). The distance between the fixed element (12) and the movable element (15) in the second position (B) is less than the distance between the two elements in the first position (A) and is substantially equal to the length of the tensioned elastic elements (4) which it is desired to form. The free end of the continuous elastic web (13) is clamped in the movable clamping element (15) when this element is in its first position (A). There is thus produced, simultaneously and substantially continuously:a relative movement between the supply source (14) and the support (11) in the direction of alignment of the clamping elements (12,15) so as to cause the supply of the continuous web (13) to the fixed clamping element (12);the translational movement of the movable clamping element (15) from its first position (A) to its second position (B) at a velocity (V<sub>2</sub>) less than the velocity (V,) of the relative movement between the web supply source (14) and the support (11), andthe supply of the web (13) from the source at a velocity (V<sub>3</sub>) less than the difference (V<sub>1</sub>-V<sub>2</sub>) between the velocity (V,) of the relative movement between the source (14) and the support (11) and the velocity (V<sub>z</sub>) of the translation of the movable clamping element (15) between the first and second positions (A,B). When the movable clamping element (15) reaches the second position (B), the web (13) is clamped by the fixed clamping element (12) whereby a piece (4) of web extends between the fixed clamping element (12) and the movable clamping element (15) in a state of longitudinal tension the degree of which is determined by the velocity difference (V<sub>1</sub>-V<sub>2</sub>) and the supply velocity (V<sub>3</sub>) of the web (13). Finally, the web (13) is cut in the region between the fixed clamping element (12) and the supply source (14), so as to separate the piece (4) from the body of the web (13) and define one of the tensioned elastic elements, and to form a new free end of the web (13) itself.

Abstract: The present invention provides a disposable absorbent article such as an incontinent pad that is both comfortable and suitable for absorbing and containing large volumes of body liquids rapidly without leakage, especially a subsequent gush of liquid. Such an absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, a layered expandable absorbent core positioned between the topsheet and the backsheet, at least two resilient shaping members, an acquisition channel, a liquid acquisition zone and at least two liquid impervious shelves. The present invention also relates to an absorbent article provided with an expandable overwrap having an expansion means for allowing the overwrap to expand when the absorbent core swells when wetted. The overwrap of the absorbent article is provided with an expansion means for permitting the overwrap to expand as the absorbent core swells when it it wetted. The expansion means is a releasable tack or other means that releases the overwrap when a slight shearing or peeling force or action is applied to the expansion means. Thus the swelling of the absorbent core is less likely to deform the shape of the pad or cause a loss of the absorptive capacity of the article, especially for subsequent gushes of liquids.

Abstract: Modern D.C.-tractioned trains and track circuit signal systems as well as high load trains need a special track construction. A new concrete cross sleeper system is provided for high load and high velocity tracks as well as for urban rapid transit systems comprising rails and sleepers having center part, connected to bar shaped ends and having reinforcing means. On the bar shaped ends two rail seats for each rail are positioned having elastic, electrically non-conducting plastic pads. The rails are fastened onto the rail seat by special tension means clamping the foot of the rail and fixed into plugs in the sleepers. This feature allows a triple point fixing of the rail at each sleeper end. Tracks on asphalt pavement may be secured by anchor device of the general type as sold under the trademark NELSON. The new track construction decreases the intermittent load of the rail/sleeper system and avoids trouble in track circuit signal systems existing in normally used prestressed concrete sleepers (FIG. 1).
