Abstract
A center-folded film splicer is disclosed. The splicer comprises a splicer assembly that is adjustably mounted to a wrapping device such that it can be moved between a storage position and an operating (or splicing) position. The splicer assembly comprises a pair of heat bars, an upper heat bar and a lower heat bar, connected with a synchronized hinge and a back-up pad bar disposed therebetween. In this manner, the upper and lower layers (or “legs”) of the films from a depleted film roll and a fresh film roll can be simultaneously sealed to each other to create a continuous film that does not need to be rethreaded through the wrapping device when replacing film rolls.
