After the glass cloth is dipped in glue, it passes between the squeezing rollers 3 and the inside of the feeding trough 5 and then is wound on the traction roller 4. The traction roller 4 drives the glass cloth to move from bottom to top. The squeezing roller 3 performs preliminary squeezing on the surface glue of the glass cloth so that the excess glue is squeezed to the edge.
