1. 1. Experimental and computational investigation of the roll forming process

   Författare :Michael Lindgren; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rollforming; Roll Forming; Flexible roll forming; Rullformning; Simulering och experimentell undersökning av rullformningsprocessen;

   Sammanfattning : One of the first questions to consider when designing a new roll forming line is the number of forming steps required to produce a profile. The number depends on material properties, the cross-section geometry and tolerance requirements, but the tool designer also wants to minimize the number of forming steps in order to reduce the investment costs for the customer.

3. 2. On the Fluid Mechanics of Partial Dewatering during Roll Forming in Paper Making

   Författare :Richard Holm; KTH; []
   Nyckelord :Fluid mechanics; roll forming; partial dewatering; capillary waves;

   Sammanfattning : The present work deals with some aspects of the fluidmechanics of paper-making,more specifically partial dewateringduring roll forming. The study is mainly experimental. Pressureand wire position measurements have been carried out in anexperimental facility, the KTH-Former,which models the rollforming zone of a paper machine. LÄS MER
