The present invention provides a tire having improved durability of a bead portion. Such methods may be employed to mitigate the occurrence of the \u201cstick-slip\u201d phenomenon during drilling. Each tilt arm is pivotally mounted at its inner and outer end portions to the base or azimuth plate of the system and to the back of the dish of the system. More specifically, a control rod extends between the handle and each of the fingers such that movement of the control mechanism between a first position and a second position produces a predetermined movement of the respective finger. The cutting device extends automatically from a retracted position to a cutting position upon the drum being rotated a constant predetermined amount by a consumer pulling on the free end of the web material.
