ABSTRACT:
An auxiliary device on devices for winding a weblike material into rolls, the quality of winding being distinctly improved, and a process for winding weblike material into rolls. In addition to the known first contact (feed) roll, the device also has a second, soft-surface contact roll the pressure of application of which can be precisely adjusted. The pressure of application of the second contact roll is transmitted by a pneumatic cylinder or a pneumatic pressure control valve, lever arms. As the diameter of the roll increases, the movement of the contact roll or the lever arms is used to generate a pulse via a contact device, so that the position of the first contact roll in relation to the roll being formed, i.e., the gap is kept constant by way of an auxiliary drive.
The device and the process according to invention are particularly well suited for winding pressure-sensitive web materials into rolls. In winding weblike material into rolls with the device according to the invention, a gap is maintained between the first contact roll and the roll being formed, the angle of approach of the web is kept constant, and the second contact roll is applied to the roll being formed at a point beyond the point of arrival of the web, in order to expel the air contained between the roll being formed and the web which is just arriving.
