Abstract: A conveyor belt includes a bottom fabric layer having a lower first surface forming a backside of the conveyor belt and an upper first surface, wherein the lower first surface is impregnated with an impregnation having: a) one or more thermoplastic polyolefins selected from the group consisting of ethene homopolymers, propene homopolymers, ethene/?-olefin copolymers, propene/?-olefin copolymers and terpolymers of ethene with two or more different ?-olefins; and b) a thermoplastic polymeric dispersing agent containing repetitive units derived from at least one ethylenically unsaturated monomer of a comparatively lipophilic nature and from at least one ethylenically unsaturated monomer of a comparatively hydrophilic nature and earring an anionic carboxylate group. A process for the manufacture of such belts includes applying the thermoplastic polyolefin(s) and the thermoplastic polymeric dispersing agent as an aqueous dispersion and heating the lower first surface having the dispersion applied thereonto.

Abstract: A joining press for joining the ends particularly of a conveyor belt, comprising lower and upper heating plates which can be engaged by pusher pads in order to apply the necessary pressure, the plates being supported by reaction beams to contain a load applied by the pusher pads, the reaction beams having seats for detachably accommodating reinforcement elements.

Abstract: Process and apparatus for continuously and permanently shaping a plate in plastic material according to an undulated profile. The apparatus includes a guide and positioning surface of the plate; a moulding and transferral wheel, peripherally shaped according to a plurality of seats, suitable for reproducing a continuous shaped profile; and a positioning, advancement and maintenance assembly in the form of a plate, peripheral with respect to the moulding wheel, of the mobile type, respectively; counter-clockwise in synchronization with the moulding and return wheel in a position independent of the moulding wheel. The assembly includes a pre-form presser, upstream of the surface involved in the shaping, set apart by at least one first stabilization and cooling presser, a moulding presser, interposed between the pre-form presser and a cooling presser; and a possible blade for detaching the plate from the seats.
