Continuous winder

A turret winder for winding web material on a spindle-supported core, in which a turret is mounted for rotation on a frame about a generally horizontal axis and carries three generally horizontally extending winding spindles movable with said turret about a circular path in an indexing manner to bring said spindles and cores thereon successively into three 120.degree. spaced stations including a web cutting and winding station, a winding completion station, and a roll removal and core replacement station, comprising a primary carriage mounted on said frame for generally vertical movement between a lowered position and an elevated position, a lay-on roll carriage mounted on said primary carriage and supporting thereon a layon roll, said lay-on roll carriage being movable between a retracted position in which said lay-on roll is retracted out of said circular path and an operative position in which said lay-on roll is positioned within said circular path and engageable with the surface of a building roll moving between said web cutting and winding station and said winding completion station, said lay-on roll carriage having an arm portion proportioned to be engaged by a turret spindle moving from said web cutting and winding station to said winding completion station when said lay-on roll carriage is in said operative position, and said primary carriage being movable by said arm portion from said lowered position to said elevated position concurrently with indexing movement of a spindle carrying building roll into said winding completion station concurrently with movement of said secondary carriage toward said retracted position as necessary to maintain contact of said lay-on roll with said building roll.

A turret winder for winding web material on a spindle-supported core, in which a turret has generally three equally spaced horizontally extending winding spindles movable by a turret about a circular path in an indexing manner to bring said spindles and cores thereon successively from a web cut-off and winding station, to a winding completion station, and to a roll removal and core replacement station, comprising a frame, a primary carriage mounted on said frame for generally vertical movement between a lowered position and an elevated position, a lay-on roll carriage mounted on said primary carriage and supporting thereon a lay-on roll, said lay-on roll carriage being movable on said primary carriage in a generally horizontal direction between a retracted position in which said lay-on roll is retracted out of said circular path and an operative position in which said lay-on roll is positioned within said circular path for engagement with the surface of a building roll moving between said cut-off and winding station to said completion station, said lay-on roll carriage having a positioning arm engageable with the spindle moving between said cut-off station to said winding completion station when said primary carriage is in said lowered position and said lay-on roll carriage is in said operative position, said primary carriage being movable by said arm from said lowered position to an elevated position concurrently with indexing movement of said building roll from said web cut-off and winding station to said winding completion station thereby maintaining a condition in which the web contacts the lay-on roll before it contacts the building roll.

A turret winder for winding paper or film material on a spindle-supported core, in which a turret has three equally spaced horizontally extending winding spindles movable by a turret about a circular path in an indexing manner to bring said spindles and cores thereon successively from a web cut-off and winding station, to a winding completion station, and to a roll removal and core replacement station, comprising a primary carriage mounted on said frame for generally vertical movement between a lowered position and an elevated position, a lay-on roll carriage mounted on said primary carriage and supporting thereon a layon roll, said lay-on roll carriage being movable between a retracted position in which said lay-on roll is retracted out of said circular path and an operative position in which said lay-on roll is positioned within said circular path for engagement with the surface of a building roll, said lay-on roll carriage having a portion in engagement with a turret spindle moving from said cut-off station to said winding completion station when said primary carriage is in said lowered position and said lay-on roll carriage is in said operative position, said primary carriage being movable by said portion from said lowered position to said elevated position concurrently with indexing movement of said building roll from said web cut-off and winding station to said winding completion station.
