Title:
ダイヘッド及びダイツーリングのスパイダー、湾曲したスパイダーレグの材料の流れ制御
Document Type and Number:
Japanese Patent JP7177844
Kind Code:
B2
Abstract:
The present invention provides a spider for a die head and die tooling that utilizes curved flow guides to direct the flow of plastic through the die head and die tooling. The spider leg splits the stream of plastic flowing through the spider into two independent streams at the upstream end. The downstream end comprises two curved flow guides that are configured to direct the two streams of plastic towards a longitudinal center plane of the spider leg. The turbulence caused by the curved flow guides creates obtuse or acute angled welding lines between the two streams of plastic. These obtuse and acute angled welding lines provide stronger bonds than the known spider legs that create butt welding or right angled welding lines.
