ABSTRACT:
The present invention relates to a leader device for initially feeding web materials between a set of nip rollers. The device comprises a pair of leg portions each having a nip roller engageable exterior surface and a web material engaging interior surface. The leg portions have connected end portions defining a leading end portion and free end portions movable apart from one another. The leg portions are configured such that a user can position leading edges of the web materials between the interior surfaces such that the leading edges are aligned with respect to one another and thereafter grasp the web materials between the leg portions by moving the leg portions together so as to engage the interior surfaces with the web materials, thereby enabling the user to insert the leading edge portion between the nip roller such that the nip rollers engage the exterior surfaces and thereafter affect nip roller rotation so as to feed the device along with the web materials through the nip rollers until the device is subsequently discharged and disengageable from the web materials. The present invention also relates to a method for feeding web materials between nip rollers.
