Abstract
An improvement in continuous-rod making machines comprises a rod-breaking mechanism, particularly for a composite filter rod, which has spaced grippers for gripping the rod and accelerating it in a generally lengthwise direction. In a preferred construction a pivoted segment carries the grippers and cam means is provided for moving the grippers together as the segment is itself moved. The segment may carry a deflector for directing the rod to waste and means may be provided for releasing the leading part of the rod after it has been broken. The new leading end of the rod on a conveyor band passes to a rod-receiving member, which may be the entry to a rod cut-off mechanism or rod-measuring device.
Claims12
A continuous rod-making machine, comprising means for conveying a continuous rod along an axial path at substantially constant speed, spaced gripping means on opposite sides of said path, first moving means for moving said spaced gripping means together and into engagement with a rod on said path to grip said rod, the gripping means being arranged to extend along and engage the rod along part of its length, and second moving means for moving said gripping means in a direction generally lengthwise of the rod and for accelerating said gripping means from rest to a speed in excess of said constant speed such that the leading part of the rod is separated from the remainder of the rod as the respective parts are pulled apart.
A rod-breaking mechanism for a continuous rod-making machine, comprising spaced gripping means on opposite sides of a rod path, first moving means for moving said spaced gripping means together and into engagement with a rod on said path to grip said rod, second moving means for moving said gripping means in a direction generally lengthwise of the rod including means to accelerate the leading part of the rod such that the leading part of the rod is separated from the remainder of the rod, and means for deflecting the rod along a deflected path, said gripping means being arranged adjacent said deflected path.
A rod-breaking mechanism for a continuous rod-making machine, comprising spaced gripping means on opposite sides of a rod path, first moving means for moving said gripping means together and into engagement with a rod on said path to grip said rod, and second moving means for moving said gripping means in a direction generally lengthwise of the rod such that the leading part of the rod is separated from the remainder of the rod, wherein the spaced gripping means includes two members adapted to grip the opposite sides of a rod, said second moving means including a segment pivoted about an axis transverse to the rod path, one of said members being fixed to said segment, and said first moving means including an arm pivoted to the segment about a parallel axis, the other member being carried by said arm.
A rod-breaking mechanism for a continuous rod-making machine, comprising spaced gripping means on opposite sides of a rod path, first moving means for moving said spaced gripping means together and into engagement with a rod on said path to grip said rod, second moving means for moving said gripping means in a direction generally lengthwise of the rod such that the leading part of the rod is separated from the remainder of the rod, and means for deflecting the rod along a deflected path, said gripping means being arranged adjacent said deflected path.
