  • Lance and slit seamed housing and method of manufacture
    Patent number: 8756809
    Abstract: A lanced and/or slit seamed housing and method of manufacture having a peripheral rolled and lanced or punched seam between a wrapper and the housing panels. The method of manufacture utilizes similar or dissimilar sheet materials in a variety of material thicknesses and with or without coatings applied prior to formation whereby a housing is formed quickly and safely. The rolling and lancing method manufactures a blower housing with an assured and positive sealed seam between the panels and wrapper of the housing. The lances or slits maintain the integrity of the seam and prevent slippage between the wrapper and panels.

  • Pass through inline seam rollformer
    Patent number: 8171766
    Abstract: A pass through inline seam rollformer having a head assembly and a cradle moveably mounted with a frame. The head assembly laterally moves upon the cradle whereby a seam may be formed upon a sheet material via tooling mounted upon the head assembly. The cradle moves relative to said frame whereby the head assembly may be retracted from a pass line of the sheet material and the sheet material may move through the apparatus without interference from the head assembly. For the preferred embodiment, the tooling utilizes one or more rollers having circumferential grooves or profiles which allow a male or a female lock seam to be formed as the head assembly moves over a leading or trailing edge of the sheet material without the need to transfer the sheet material 90 degrees or remove the sheet material from a production line.
