Spacing between rollers - Limberoller

The distance between the LIMBEROLLER® can be influenced by the stiffness of the belt, especially when using a very soft belt. It is recommended that the user contact the tape supplier to determine the maximum spacing between the rollers, taking into account the trough angle used (see paragraph 4).
