METHOD FOR CONNECTING TWO JOINING SURFACES
20230294365 · 2023-09-21 ·

The cutting of fibrous material which does not melt easily is effected to avoid the unravelling of cut edges, using ultrasonic or laser beam techniques. The method includes (a) applying a thermoplastic powder material to the cutting region, and (b) applying thermal shock to the localised area, sufficient to destroy the fibres of the material, and melt the powder on either side of the cut, and (c) pressing the cut edges while the fused thermoplastic powder is still soft. Woven or non-woven fabrics have tendency to unravel, after cutting, and normally require a sewn hem. The method of the invention disposes of the sewn hem, and provides a thermo-cutting technique applicable to non-fusible or non-thermoplastic fibres.

An apparatus for realising a cardboard strip for packaging by consecutively joining a plurality of cardboard sheets for packaging to one another
20210347139 · 2021-11-11 ·

The apparatus (100) for realising a cardboard strip for packaging comprises: a store (M), for a stack (P) of cardboard sheets (C); gripping means (4), for picking up a cardboard sheet (F1) from the stack (P) and for positioning the second cardboard sheet (F1) on the first support (1) for the application of adhesive material; transfer means (6), for transferring the first cardboard sheet (F1) towards the second support (2), so that the first cardboard sheet (F1) is rested on the second support (2) with an end portion (E) thereof with the adhesive material projecting towards the store (M) and towards a third support (3).

The third support (3) is activatable into a raised configuration (S), to raise an end portion of a second cardboard sheet coming from the store and into a lowered configuration (A) so as to lower the end portion (E2) of the second sheet (F2) and position it at the end portion of the first sheet (F1). Pressor means (7) are activated transversally to the two sheets (F1, F2) so as to press the two superposed end portions (E, E2) of the two sheets (F1, F2) in order to fix the end portions (E, E2) to one another to form a cardboard strip (NC).

Dielectric heating of foamable compositions

A method for dielectrically heating foamable composition to foam and set the composition is described. In particular, radio frequency (RF) heating is used to heat the foamable composition to provide insulation in the manufacture of an article.

EMBOSSED TISSUE
20230374733 · 2023-11-23 ·

Disclosed are embossed multi-ply tissue products having improved bulk, softness, strength, embossment clarity and/or embossment height. The multi-ply tissue products comprise a first tissue ply having a plurality of embossments arranged in an open first pattern such as open, continuous line elements, which may be substantially oriented in the cross-machine direction (CD). The products further comprise a second ply having a plurality of micro-embossments disposed in a second pattern. The first and second embossing patterns are such that when the first and second plies are joined to form the product the first and second patterns are not in registration with one another.
