A method of preparing a window panel with a resinous frame, comprises relatively moving a window panel and a die for extruding a resinous material so that the die is moved along a peripheral portion of the window panel, and extruding the resinous material from the die in a predetermined shape to form a shaped product for a resinous frame on the peripheral portion of the window panel; wherein the relative movement of the die and the window panel is carried out by using an operating robot which has been taught a track to follow; and wherein the operating robot has been taught another track so as to separate the die and the panel when the die has moved around the peripheral portion of the window panel and has returned at a position just before a beginning of the shaped product, thereby to form the frame on the window panel in a one-piece construction.

Method for preparing a plate member for a window with a resinous frame

A method of making by extrusion-molding an elongated window frame used for a window panel of a vehicle is to use an extrusion molding die which includes a slide core defining the cross-sectional shape of the window frame, and to move the slide core in the extrusion-molding die so that the cross-sectional shape of the window frame is continuously changed along the direction of the length.

Method of making a window frame and a window panel with a window frame

A method of making a window panel with a synthetic resin frame comprising forming a synthetic resin frame by extruding synthetic resin through a die into a specified shape along a peripheral portion of a plate-like material for a window on at least one surface of the plate-like material, and curing the formed synthetic resin frame so that the synthetic resin frame is formed integrally with the peripheral portion of the plate-like material, characterized in that the die is moved to trace a locus along a peripheral portion of the plate-like material which has been previously inputted, and the locus and the angular position of the die are corrected by detecting a position of the end face of the plate-like material, whereby the synthetic resin frame having a specified shape is formed.

Method of making a window panel with a synthetic resin frame

A method for producing a sheet or film of a transparent synthetic resin, which comprises discharging onto a continuous substrate moving in one direction a synthetic resin material for the transparent synthetic resin from a discharge die having a linear outlet extending perpendicular to the moving direction of the substrate, casting and curing or solidifying the resin material on the substrate to form a sheet or film of the transparent synthetic resin, wherein the discharge die is continuously or intermittently reciprocated in a direction substantially perpendicular to the moving direction of the substrate.
