Vertical impregnation bath for pultrusion lines

A vertical impregnation bath for a pultrusion line, comprising:

• a vertically-oriented reservoir having an inlet adjacent a top end of the reservoir and a terminal area at a bottom end of the reservoir;
• wherein the inlet is larger than the terminal area of the reservoir and the inlet is higher than the terminal area of the reservoir,
• the reservoir further having an outlet adjacent to the terminal area, and
• at least one of an inner guide plate within the reservoir, an upper guide plate adjacent to the inlet, and a guiding shaft within the reservoir.

A method of impregnating rovings with a resin on a pultrusion line, comprising the steps of:

• providing a vertical impregnation bath as a component of the pultrusion line, the vertical impregnation path comprising:
• a vertically-oriented reservoir having an inlet adjacent a top end of the reservoir and a terminal area at a bottom end of the reservoir;
• wherein the inlet is larger than the terminal area of the reservoir and the inlet is higher than the terminal area of the reservoir, and
• the reservoir further having an outlet adjacent to the terminal area;
• and
• pulling the rovings through the vertical impregnation bath from the inlet to the outlet and through a die adjacent to the outlet.
