Method for forming coiling edge in hand holding end of paper board pipe

公开了一种在纸板棉塞管手持端形成改进的手指把手的方法。该手持端具有一个向外卷起的边缘，其制造过程为：施加水分到直径小于约25mm纸板管的手持端，将一个成形工具加热至约100°F到约350°F，以约50r/min到1000r/min的速度相对于成形工具转动纸板管，以及使纸板管手持端与成形工具接触约0.2到约5秒。这样，成形工具将纸板管手持端向外卷起，在纸板安放器管手持端的外侧形成一个圆弧形曲面。同时公开了最后得到的棉塞安放器。 A method of forming an improved finger grip at the gripper end of a paperboard tampon tube is disclosed. This gripper end has an outwardly rolled edge produced by applying moisture to the gripper end of the paperboard tube having a diameter of less than about 25 mm, heating a forming tool to about 100 DEG F. to about 350 DEG F., rotating the paperboard tube with respect to the forming tool at a rate of about 50 to 1000 rpm, and contacting the gripper end of the paperboard tube with the forming tool for about 0.2 to about 5 seconds. In this manner, the forming tool rolls the gripper end of the paperboard tube outwardly to form a radiused surface at the outside of the gripper end of the paperboard applicator tube. The resulting tampon applicator is also disclosed.
