ABSTRACT:
The invention provides a method an apparatus for joining at least two webs or running lengths of material together by means of at least one strip of adhesive applied to at least one of the webs in such a manner that the consumption of adhesive is reduced and greater reliability is achieved. This is made possible by using an adhesive having a viscosity which is close to the viscosity of water and causing the adhesive to be acted upon by a low pressure and to be filtered prior to application to the associated web.
