用于解卷在卷筒中卷绕的材料片材的方法和套件
摘要：
本发明涉及一种解卷在卷筒中卷绕的材料片材的方法，所述方法包括：提供卷曲片材的卷筒，所述卷筒限定外表面并且包括从所述卷筒解卷的片材的自由部分；在所述卷筒的外表面上布置压缩元件，从而限定接触线，所述接触线是将所述片材的自由部分与所述卷筒的其余部分分离的线；借助于所述压缩元件在所述接触线处以介于约(4)牛顿至约(16)牛顿之间的力压紧所述卷曲片材的外表面；以及通过在解卷方向上拉动片材从所述卷筒解卷片材。
摘要（英）：

The invention relates to a method to unwind a sheet of material wound in a bobbin, the method comprising : providing a bobbin of a coiled sheet, the bobbin defining an outer surface and comprising a free portion of the sheet unwound from the bobbin; arranging a compressing element on the outer surface of the bobbin, so as to define a contact line, the contact line being the line separating the free portion of the sheet from the rest of the bobbin; pressing by means of the compressing element the outer surface of the coiled sheet at the contact line with a force comprised between about (4) Newton and about (16) Newton; and unwinding the sheet from the bobbin pulling the sheet in the unwinding direction.
