Title: Method and device for handling web of thin film magnetic recording medium
Inventor: TAKEDA HIDEO
IPC: C08J7/00
Filed: 1990-10-19
Abstract: PURPOSE:To prevent the wrinkling of a web under running even under a low tension without using any complicated device by forming a running passage into S-shape by the outer circumference of a roll pair at the time of continuous running of a web, bending the web by the upper stream side roll so as to be pulled to both lateral end sides, and guiding the web by the other roll so as to restore the bending. CONSTITUTION:As the axial sectional form of a crown roll 2 is properly curved so that the roll cross directional center diameter is large and the diameter on both end sides is small, a web 5 in contact with the outer circumference of the roll 2 receives a force as being slightly stretched in the web cross direction according to the curvature of the roll outer circumference. Therefore, when the web 5 takes a motion as shifting from the center line of a route, a force as returning this shift is generated to regulate the movement in the web direction from a slight tension added to the web, and a centering effect as regularly positioning the web on the running center line is worked. Thus, the wrinkling of the web under running can be effectively prevented even under a low tension without using any complicated device.
