| 摘要 |
The invention relates to a machine for producing a tubular product (T) by means of helical winding of strips of web material, comprising a mandrel ( 4 ) and a winding member ( 7 ) to helically wind the strips (S 1, S 2 ) of web material around said mandrel. To improve adhesion between the strips at least one pressure member ( 31 ) is provided, cooperating with the mandrel, disposed downstream or upstream of the winding member ( 7 ) with respect to the direction of advance (fT) of the tubular product being formed on said mandrel. The pressure exerted by the pressure member promotes adhesion of the strips forming the product.
