Abstract: A film splicer apparatus is disclosed for splicing a film used for bagging snack foods. The apparatus includes a frame and an axle which is rotatably supported by the frame for rotatably supporting a first roll of the film used for the bagging of the snack foods. A further axle is disposed spaced from the axle for rotatably supporting a replacement second roll of film for replacing the first roll of the film when spent. The first roll and the replacement second roll are rotatable about a first and second axis respectively, the first and second axes being disposed spaced and parallel relative to each other. A tail grabber is provided for grabbing a tail end of the spent first roll. Also, a tracking control is used for tracking the tail end of the spent first roll. A registration device is controlled by the tracking control for registering the tail end of the first roll with an aligned leading edge of the replacement second roll.

Abstract: Apparatus for drawing a web of sheet material from a roll wound on a core which is supported to rotate freely about its axis as the web is drawn off the roll. A brake has a movable element connected to a shaft which is rotatable about the axis of the core independently of the core. First and second coaxial members are mounted to turn with the shaft and are mounted for independent axial movement toward and away from the core. When the first member is moved axially into frictional engagement with the core, the core turns the shaft. When the shaft is turning in unison with the core, the second member is moved into interlocking engagement with the core to mechanically connect the core and the shaft.

Abstract: Apparatus for continuously supplying a web of sheet material wound on rolls includes a conveyor which carries a roll from a loading station to a splicing station and then to an active or running station. While a running web is being drawn off a roll at the active station, a standby roll is loaded on the conveyor at the loading station and then it is advanced to the splicing station. A stationary core brake located at the active station is responsive to the tension of the running web and applies a drag to the core on which the web of the active roll is wound to maintain the tension at a selected level. When the web on the active roll is nearly exhausted, an endless belt in frictional engagement with the standby roll is driven by a motor and accelerates the roll until the peripheral speed of the latter is equal to about 99 per cent of the linear speed of the running web and then the belt is driven from the running web so that the two speeds match.
