Abstract
A splicing apparatus has a drum rotatable about a drum axis adjacent a web roll and having a generally cylindrical outer surface centered on the drum axis. A pair of suction bars on the drum defining thereon an axially extending and radially outwardly open slot each have an outer surface and are each pivotal about an axis generally parallel to the drum axis between a rest position with the bar surface forming a respective part or continuation of the outer surface of the drum and a holding position with its surface pressed angularly against the other bar so that in the holding position a web end can be clamped between the bars. Air is aspirated through the surfaces of the bars to adhere the web to the drum. The drum can be rotated about the drum axis and can be moved to displace the drum into engagement with the web.
