    Abstract: A process for the continuous manufacture of phenolic resin foam in an endless sheet which includes mixing expandable liquid phenolic resin with a blowing agent and an acid-containing curing agent, optionally with the addition of additives, and processing of the mixture in a temperature-controllable double belt press. The process also comprises cooling the phenolic resin to a temperature of from about 8* to 15*C., admixing a blowing agent under a high pressure with said resin to form a resin premix, mixing said resin premix with a curing agent resin to form a resin premix, mixing said resin premix with a curing agent and other foam additives to form a curable reaction mixture, continuously applying said mixture uniformily onto a moving substrate, covering the mixture on said substrate with a continuous protective layer, passing the covered mixture into the double belt press, and foaming the mixture under pressure until a desired sheet thickness has been obtained.

    Abstract: An apparatus and method for the continuous production of wound pipes from an extruded profiled strip. In order to compensate for deviations in the speed of the strip being supplied by an extruder, a control mechanism for controlling the speed of the wind-up drum in dependence on the magnitude of the sag in the profiled strip at a position intermediate the extruder and windup drum is provided. To further accommodate any deviations in a cross-sectional size of the profiled strip, a cooled sizing shoe is provided for shaping the outer contours of the pipe formed by the connected-together, spirally wound extruded strips. In order to cut the completed pipe in a single plane perpendicular to the axis of the pipe, without circumferentially moving the cutting apparatus, and while maintaining the winding mandrel continuously rotating, a cutting mechanism control means is provided which axially moves the cutting mechanism at the same speed as the axial movement of the completed pipe along the mandrel.

    Abstract: THE DEVICE INCLUDES GLAZING ROLLERS OR ROLLER ASSEMBLIES USED TO PRODUCE PLASTIC FOILS, STRIPS OR THE LIKE FROM VISCOUS PLASTIC MASSES. THE MASS IS INSERTED BETWEEN THE ROLLERS OR IN THE ROLLER ASSEMBLIES SO THAT THE PLASTIC MATERIAL PASSES BETWEEN THE ROLLERS AND IS PRODUCED IN THE REQUISITE FORM OF A FOIL, STRIP OR THE LIKE.
