Abstract
An underblanket of the blanket of a blanket cylinder of a printing press, particularly of the offset type, consists of a multilayer structure comprising a first layer comprising at least one polyurethane-based material, and at least a second layer comprising at least one polyurethane-based material, which is different from the one forming said first layer, and directly joined with said first layer by exploiting the intrinsic chemical/physical compatibility.
Claims9
An underblanket of a blanket of a blanket cylinder of a printing press, the underblanket that is a multilayer structure consisting of:
- a first layer having a polyurethane-based material and
- a second layer having a polyurethane-based material different from the polyurethane-based material of the first layer, the second layer being directly joined with the first layer,
- wherein one of the first layer and the second layer is a polyurethane-based material having an E-modulus of 2130 MPa+/−20% according to ISO527.
A blanket cylinder of a printing press comprising
- a blanket having an underblanket that is a multilayer structure consisting of a first layer having a polyurethane-based material and a second layer having a polyurethane-based material different from the polyurethane-based material of the first layer, the second layer being directly joined with the first layer, wherein one of the first layer and the second layer is a polyurethane-based material having an E-modulus of 2130 MPa+/−20% according to ISO527.
A printing press comprising a blanket cylinder including a blanket having an underblanket that is a multilayer structure consisting of a first layer having a polyurethane-based material and a second layer having a polyurethane-based material different from the polyurethane-based material of the first layer, the second layer being directly joined with the first layer, wherein one of the first layer and the second layer is a polyurethane-based material having an E-modulus of 2130 MPa+/−20% according to ISO527.
