  • Patent number: 5934461
    Abstract: A method for forming an aluminum cigarette package includes the step of cutting elliptical blanks from an aluminum sheet and shaping the blanks by progressive drawing operations into a lid and a body. The lid and body are joined by a flexible label that serves as a hinge that allows the lid to be pivoted relative to the body to open and close the pack. In an alternative embodiment of the invention, a drawn aluminum body is provided with a flat cap member having an aperture and a resealable closure. The invention includes a metal package made by the method of the invention.

  • Patent number: 5688161
    Abstract: A sharpening and cleaning apparatus for sharpening scalloped-edged blades in a carton slitting machine includes at least two rotating cylindrical hones mounted on a pneumatically controlled actuator, and a pair of blade cleaning brushes mounted on a separate actuator. A sharpening operation is initiated by a machine operator as needed to maintain blade sharpness, and is performed automatically by the apparatus controls. The hone actuator positions the rotating hones in contact with opposing sides of a cutting edge of the slitting blade as the blade moves past the hones at reduced speed. A first hone is rotated in a direction opposite to the direction of the blade and a second hone is rotated in the same direction of the blade. During sharpening, the hones execute several reciprocating axial movements to stroke the blade. Prior to the operation of the hones the actuator positions the brushes in contact with the blade and causes the brushes to rotate to remove debris from the blade.

  • Patent number: 4914862
    Abstract: A spring loaded safety member is pivotally mounted against a coil spring seated within the channel of a standard pulley and spring system which has been moved slightly in the channel. The safety member comprises sharp teeth and is normally retracted in the channel with a curved portion around a pin extending laterally therethrough. Upon failure of the cord or spring of the standard window system the safety member suddently pivots outwardly under spring pressure to engage the inner wall of the window frame.
