Abstract
The specification discloses an improved platen for a paper roll header. The platen has a two-piece face including an inner circular portion and an outer portion eccentrically surrounding the inner portion. The two face portions are independently heatable enabling the outer portion alone to be heated in certain applications to adhere a head to the periphery of a particular size roll.
