ABSTRACT:
A lap splicing apparatus for lap splicing first and second webs together, with each of the first and second webs alternately constituting a running web and a new web to be spliced to the running web, includes a frame; a first spindle mounted at a first fixed position on the frame for holding a roll containing the first web at a first orientation; a second spindle mounted at a second fixed position on the frame for holding a roll containing the second web at the first orientation; a single lap splicing device immovably mounted at a fixed position on the frame for lap splicing the first and second webs together with the trailing tail end of the lap splice always being on the same side; a first transfer assembly of rollers for bringing the first web to the lap splicing device, and for turning the first web by at least one angle from the first orientation; and second transfer assembly of rollers for bringing the second web to the lap splicing device, and for turning the second web by at least one angle from the first orientation, such that the running web is at a first level and the new web is at a different, second level prior to the lap splicing operation, with the new web moving from the second level to the first level after the lap splicing operation.
