ABSTRACT:
An improved braking system for a rotatable roll support hub for a roll product of web material is capable of providing a smoother and progressive braking action which uses a less powerful compression spring. This can be achieved by utilizing a friction element that has frustoconical shaped friction surfaces. Specifically, the friction element comprises a frustoconical disc that floats between a similar frustoconical surface that rotates with the roll support hub and an opposite similar frustoconical surface on the pressure disc. Preferably, a rim flange is provided as part of the pressure disc that forces the friction element into wedged engagement on the frustoconical friction surface of the roll support hub. The advantages are achieved for providing a smoother progressive braking action which is applicable to any roll support hub on which a controlled braking force is desirable. Such may include manual tape dispensers or any other roll support hub for any roll of web material which is associated with an automatic, semi-automatic, or manual dispensing or applying apparatus.
