To clean bobbin sleeves placed on bobbin carriers, a sleeve monitor (24) sends data to a control (27) on the dimensions and location of any residual yarn winding (72) still on the sleeve (41). The control (27) activates the sleeve stripper according to the measured data. Also claimed is an assembly with a sleeve monitor (24) at the distribution path (9), to measure the dimensions and location of a...

The invention relates to a vehicle tyre tread (10) which is made up of tread pattern segments (3) of an elastic material (F), adjacently positioned in the orientation of the tread and separated one from another by grooves (2). The tread pattern segments have sipes (5a) in each of which the opposed faces (16a, 16b), transverse to the outer surface (9) of the tread, are substantially parallel. The s...

Expanded thermoplastic resinous materials are obtained by mixing styrene-based polymers having mainly a syndiotactic configuration or a thermoplastic resin composition containing said styrene-based polymer and a foaming agent, and then heating the resulting mixture. These expanded materials are excellent in heat resistance and are usefully employed in applications where high heat resistance is nee...

Expanded articles of biodegradable plastics material are produced by the extrusion of a composition including starch, a polymer compatible with starch, in particular, an ethylene-acrylic acid copolymer and/or ethylene-vinyl alcohol copolymer, and an expanding agent. Preferably use is made of sodium bicarbonate as expanding agent in the presence of a polymeric acid.

A concrete substrate (1) carries a layer (2) of contact adhesive to which plastering (3) is applied. The layer (2) of contact adhesive fills and/or covers the irregularities (5, 6) on the surface (4) of the substrate (1), providing the plastering (3) with a surface which is free from irregularities so that the plastering (3) is bonded over its whole area to the concrete substrate (1).
