A winding apparatus for sheet-shaped molding material wherein slippage in the width direction can be prevented when the sheet-shaped molding material is wound around a winding core tube, because side plates are detachably mounted on both ends in the axial direction of the winding core tube. Thus, the slippage during the winding operation can be prevented, so that the weight of the molding material being wound can be increased, whereby a thick, wide thick molding compound can be rolled.

Winding apparatus for sheet-shaped molding material

An apparatus for continuously manufacturing a sheet of molded compound includes a first conveying unit for continuously conveying a lower film. First and second impregnation rollers are provided above the lower film for impregnating a viscous material and a solid material to obtain a compound mixture to be dropped onto the lower film. First and second scraping rollers are provided below the first and second impregnation rollers to scrape the compound mixture from the impregnation rollers. A scattering roller is provided below the first impregnation roller upstream from the first scraping roller relative the feed direction of the lower film. The scattering roller is positioned to act upon rotation to prevent scattering of portions of the composite mixture caused at least in part by the first scraping roller. A second conveying unit is provided for conveying an upper film. Included in the second conveying unit is a guide roller positioned below the second impregnation unit downstream the second scraping roller relative the feed direction of the lower film. The guide roller is positioned with the upper film disposed thereabout to prevent scattering of portions of the composite mixture caused at least in part by the second scrapping roller. Supply pipes are provided for supplying the viscous material which are disposed above the first and second impregnation rollers. Each supply pipe includes a plurality of openings which have varying opening areas to compensate for a decrease in an internal pressure of the supply pipe as the viscous material flows within the supply pipe.

Manufacturing apparatus for sheet-shaped molding material including a

A sheet-shaped molding material, comprising carrier films having therebetween a paste-like curable material including resin, filler, and reinforcing solid material of glass fiber. The elongation percentage of the carrier films is 1% lower with respect to the tension of 20 kg per m, to remove the curvature and bending of the material caused during the winding, and also to equalize the thickness of the material.
