  • Patent number: 10046472
    Abstract: A rotating log saw clamp for clamping a product roll to be sawn. The rotating log saw clamp includes a first portion disposed for rotation about an axis and a second portion disposed for rotation with the first portion and movable relative to the first portion between an open position and a clamping position. The second portion is rotatable from the clamping position to the open position by relative rotation of the first and second rotating portions.

  • Patent number: 6508153
    Abstract: The conveyor product transfer apparatus of the present invention includes at least one product transfer member mounted for translational (and preferably reciprocating) movement between product conveying surfaces or between a discharge or receiving station and a conveying surface separated by a distance sufficient to provide equipment clearance for an operation performed upon product transferred by the transfer member. Preferably, each transfer member is mounted for reciprocating translational movement between ends of conveying surfaces that are separated a distance apart, and has a sliding member in sliding engagement with a track to facilitate such movement. Each transfer member is coupled to an actuation assembly for movement thereof. The actuation assembly is preferably a camshaft assembly. To support the conveyed product during product processing operations (e.g.

  • Patent number: 5643398
    Abstract: An apparatus and method for sealing a loose tail of wound material against a log using an infeed and log reject station, a tail separator station and a tail ironing and log discharge station. The apparatus and method receives a log on a pair of rider rolls and directs one or more air jets against the log to cause the tail to extend away from the log and captures the tail on a vacuum table as controlled by an optical sensor monitoring the table. The log then progresses to a glue table where a stripe of glue is applied through an aperture in the table by a glue transfer bar rotating out from being submerged in a glue reservoir. The log is then received between three ironing rolls which compress the tail against the log and discharge the log from the ironing rolls by moving an ejector arm from a rest position between two of the ironing rolls towards the third ironing roll to an ejecting position intermediate all three ironing rolls.
