<p>During a paper making process, a paper web is de-watered by a porous de-watering web consisting of longitudinal (2, 3) and transverse (5, 6, 7, 8) strips. Longitudinal and transverse strips are each made of a different type of fibre, and are joined at their crossover points (8, 16, 17) esp. by local application (9) of a hotmelt bonding agent. Also claimed is a process for making the de-watering web in which the crossover joins are further strengthened by a form-fit union in which each strip incorporates a shallow groove with a thread which is transverse to the adjacent thread. The union is effected by insertion of a single pin through the two strips.</p> |
