A windshield molding is installed in the space between a windshield and a periphery of a window opening of a vehicle body panel. The windshield molding comprises a pair of extruded side molding parts, a pair of extruded corner molding parts, and an extruded upper molding part integral with and extending between the side and corner molding parts. Each of the side molding parts associated with each side edge of the windshield is larger in thickness compared to the upper and corner molding parts, where a water drain channel is formed.

Automobile windshield molding and the method of producing the same

This invention aims to shorten cycle time by allowing a robot to be operated with speed capability regardless of the shape of moldings. An extrusion molding apparatus has an extrusion molding machine which delivers an extrusion material which becomes a frame-shaped molding through a nozzle fore end, and a robot which holds a workpiece on which the molding is formed and whose working speed is set so as to make travel speed of workpiece rectilinear portions with respect to the nozzle fore end higher than travel speed of workpiece corner portions with respect to the nozzle fore end. Thus, changes in workpiece travel speed with respect to the nozzle fore end are allowed, and robot working speed is not restricted by the shape of moldings.

Extrusion molding apparatus and an apparatus for controlling the same

An extrusion molding machine for manufacturing a panel unit including a panel and a frame mounted on a peripheral edge of the panel. The extrusion molding machine includes molding die for forming the frame on the peripheral edge of the panel by extrusion molding. The molding die are adapted to follow the fluctuation of the peripheral edge of the panel caused by variation of curvature of the panel.

Extrusion molding machine

A windshield molding which drains rainwater smoothly through the rainwater groove provided at necessary sections and having different depth in the longitudinal direction for better drainage and which can be produced simply and continuously as a single molding without the addition of cutting or other processes.

A production method for extruding molding sections to be fitted in a periphery of a windshield glass includes the steps of extruding the molding sections by using a die having an opening for extruding a support leg which is to be inserted into a space between the windshield glass and a window frame of a body panel and having an opening for extruding a decorative portion which covers the space from outside the molding sections, wherein the molding sections are extruded by keeping an area of the extrusion opening on the die for the decorative portion constant at all times. The method includes the step of increasing, during production of one of the molding sections, an area of extrusion opening on the die for extruding the support leg in order to provide an enlarged thickened section between an outer surface of the windshield glass and the decorative portion. In addition, insertion of an additional die into the extended section of the extrusion opening on the die of the support leg is possible with specified timing so as to form a rainwater groove on the sidewall of the enlarged thickened section by partially shielding the enlarged thickened section.

A windshield molding which drains rainwater smoothly through the rainwater groove provided at necessary sections and having different depth in the longitudinal direction for better drainage can be produced simply and continuously as a single molding without the addition of cutting or other processes. The windshield molding includes a support leg, a decorative portion, an enlarged thick section provided in the support leg and a rainwater groove opening to the inner periphery of the windshield of the windshield molding.

An automobile windshield molding is provided to be fitted in a gap formed between an automobile window frame and an automobile windshield. The molding includes an upper molding and opposing side moldings formed monolithically and continuously with the upper molding. The portions of the upper and side moldings which extend above the windshield are formed thicker for the side moldings than for the upper molding, in order to prevent sideways scattering of water incident on the windshield. The thickness of the side moldings decreases gradually toward the upper molding. The molding can be formed by a molding apparatus utilizing shutters which have predetermined shapes and which are linearly movable in order to increase or decrease the effective size of the extrusion opening to gradually change the thickness of the moldings during continuous molding of the upper and side moldings.

Molding for automotive front glass and molding apparatus

A method of manufacturing a windshield molding by the extrusion process. The molding includes a pair of extruded side molding parts and an extruded upper molding part integral with and extending between the side molding parts. The side molding parts have large thickness portions where water drain channels are formed. The water drain channels have sufficient capacity to guide fluid such as rain water from the outer surface of the windshield.

Each of side molding parts associated with each side edge of the windshield is larger in thickness compared to the upper and corner molding parts, having a water drain channel which extends in and along such large-thickness part.

Automobile windshield molding

An automobile windshield molding is produced by a molding machine having dies. A method of producing the molding includes the step of extruding molding material through a hollow portion formed by the dies. The shape of the hollow portion is changed by moving the dies according to the cross-sectional shape of the molding, thereby widening part of the hollow portion of the dies to increase the thickness of the molding material. One of the dies is projected into the widened part of the hollow portion to form a water drain channel on a large thickness portion of the molding.

Method of producing automobile windshield molding

A molding is disclosed and is adapted to be fit into a gap defined about a periphery of an automobile windshield between the windshield and a window frame of the automobile. The molding includes a main body portion including an elongated upper molding section adapted to extend along an outer periphery of the windshield, and a pair of elongated side molding sections adapted to extend along opposing side peripheries of the windshield. Each of the upper and side molding sections includes an inner portion adapted to extend into the gap between the windshield periphery and the window frame, and an outer portion adapted to overlie an outer surface of the windshield. The outer portion has a rain water guide groove formed therein longitudinally along a side of each of the side molding sections. The guide groove is gradually reduced in thickness along the elongated main body portion from predetermined locations on the side molding sections to predetermined locations on the upper molding sections, such that the guide groove is gradually reduced in width and is absent along substantially an entire length of the upper molding section. In addition, the molding includes a decoration member bonded to an outer surface of the main body portion. The elongated main body portion is a continuous unitarily molded element.

Molding for windshield of automobile and its molding apparatus

A molding for a windshield has an upper molding portion, corner molding portions integral with opposite ends of the upper molding portion and side molding portions integral with the corner molding portion. Only the side molding portions have a groove lip extending therefrom for defining a rain water guide groove. The groove lip of each side molding portion has a projection length which progressively increases from the corner portion to the side portions. Further, each of the molding portions has an upper decoration portion, a lower clamp lip and a metal fitting connecting the upper decoration portion to the lower clamp lip.

A sterilizing/deodorizing apparatus having a fan for creating an air flow in one direction in a box-like body. The body has divided air passages, one of the air passages having an ozonizer and an air-permeable ozone-decomposing catalyzer, and the other air passage simply allowing untreated air to flow therethrough.
