Abstract: The present invention relates to a process for the continuous production of prepreg sheets unidirectionally arranged in parallel which involves contacting a plurality of fiber bundles arranged unidirectionally in parallel with each other with a solvent and continuously taking up the individual fiber bundle units under tension over curved surfaces of spreader bodies, such as cylinders while in a wet state, thereby spreading out said fiber bundles over the curved surfaces by means of said tension and subsequently drying the thus-spread out fibers. The invention also contemplates impregnating the dried fiber bundles with a specified quantity of molten resin to prepare the final prepreg resin-containing sheets.

Abstract: A cross hammer type dot printer comprises a rotary drum having an outer peripheral surface formed with a plurality of projections extending along its longitudinal axis, and a printer head disposed in front of the drum and movable in a direction which is perpendicular to the direction in which a recording medium is fed. The printer head faces the drum in a way in which it substantially crosses the projections on the drum, and includes an electromagnetically operable printing hammer. The projections are displaceable vertically relative to the printing hammer upon rotation of the drum, while the printing hammer is horizontally displaceable relative to the projections upon movement of the printer head, so that when the hammer strikes against the projections, dots are printed where they cross each other. The printer head of this invention is suitable for use in such a cross hammer type dot printer. It can be made of a small number of parts, and is small.

Abstract: A print head travelled lengthwise with respect to a cylindrical rotary drum provided on its outer periphery with a plurality of ridges extending parallel to the axis has two or more print hammers electromagnetically driven. The print hammers are arranged parallel to one another at a distance corresponding to a horizontal pitch of a dot matrix and are changeably driven with intervals which the corresponding ridge of the drum requires to move a vertical pitch of the dot matrix. Further, in order to avoid a bad influence of a nonuniformity of rotation of the drum to the printing quality, the print hammers have a plurality of bumps for forming dots on the respective striking surfaces and each of the ridges has a periphery surface of a width greater than a thickness of the print hammer.
