Description

Technical Field

[0001] The invention relates to color steel plate production equipment, in particular to a heat-insulating cotton strip feeding machine. Background Art

[0002] Insulation cotton strips are important insulation materials installed between two layers of color steel plates during the production of color steel insulation boards. During the production of color steel insulation boards, firstly, glue is applied to the upper surface of the lower color steel plate, and then the insulation cotton strips are tightly attached to the upper surface of the lower color steel plate, and then glue is applied to the lower surface of the upper color steel plate, and the upper color steel plate is attached to the upper surface of the tightly arranged insulation cotton strips.
