Resistant funnel for testers of blinds has support plate that is placed by positioning augers in mold before injection process

摘要

The main body has parallel walls in between which a mouth and an outlet are formed and which define a slide channel having a bottom wall. A straight handle aligned with the slide channel is connected to the rails of a door or window. The bottom wall has a resistant covering which may be in the form of a metallic plate that is resistant to wearing. The metallic plate has a central body and side fins with augers that can be penetrated by plastic material in which the pike of the funnel is molded. A support plate is placed in a mold before an injection process by positioning augers. An independent claim is also included for a method of production of a resistant funnel.
