ABSTRACT:
A heat seal splice assembly for heat splicing first and second webs together, with each web alternately constituting a running web moving in first direction and a new web to be spliced to the running web upon depletion of the running web from a roll, includes a central guide having first and second sides, with the first web being located to the first side of the central guide and the second web being located to the second side of the central guide, the central guide having a hold down assembly for holding the new web to the central guide, a rotation assembly for rotating the central guide such that the new web held to one side of the central guide can be positioned to an opposite side of the central guide at which the running web is positioned, a clamping assembly for clamping the first and second webs together, a first heat seal assembly movable toward and away from the first side of the central guide to heat seal the first and second webs together against the first side of the central guide when the first and second webs are positioned at the first side of the central guide, and a second heat seal assembly movable toward and away from the second side of the central guide to heat seal the first and second webs together against the second side of the central guide when the first and second webs are positioned at the second side of the central guide.
