  • Solenoid coil attachment mechanism
    Patent number: 6000679
    Abstract: A solenoid coil attachment mechanism includes a coil assembly with a wire end that projects from the coil assembly and an extending elongated leg that includes a latching mechanism. A carrier has a wall with an opening receiving the leg of the coil assembly and has a wire guide that is funnel shaped, has an open end and receives the end of the wire. A circuit board is attached to the carrier and the wire end is soldered directly to the circuit board.

  • Method for applying a tractive force to a stack of tissues with reduced bulk loss
    Patent number: 5690263
    Abstract: During tissue converting operations, a tissue "sausage" is conveyed between a pair of converging tractive belts to a cut-off saw where the sausage is cut into individual clips of tissue. Tissue bulk is preserved by providing the tissue-contacting surfaces of the belts with spaced-apart protrusions which cause the tissue sausage to assume a profile approximating a sine wave. The sine wave profile increases the tractive force of the belts, which in turn allows a lowering of the compressive load exerted by the belts on the tissue sausage. As a result, the bulk loss of the tissue sheets within the sausage is reduced.
