Definitions

  • This invention relates generally to spring assemblies for
  • each coil spring is encased within its own fabric sack or pocket.
  • the sack or pocket is typically defined
  • strip is generally formed by folding a strip of double width fabric
  • springs are inserted between the plies with the axes of the springs
  • pocketed coils are passed through a turner assembly during which
  • the springs are reoriented typically about 90° within the fabric
  • transverse seams defining individual pockets.
  • the springs are beaten by paddles
  • the present invention overcomes the above described
  • the pocket according to this invention avoids the need for turning or
  • the present invention preferably begins with the
  • the present invention is a
  • the springs are maintained in a compressed configuration between
  • thermally weldable material preferably the longitudinal seam
  • the longitudinal seam of the fabric Preferably, the relaxation and
  • the wheels include a plurality of
  • the springs are supported during their
  • individual pockets are formed preferably by a transverse weld head
  • the transverse seams are formed in the fabric to
  • pair of opposing and rotating transport wheels indexes or moves the
  • False loft occurs when the
  • pocketed coil string may become crushed thus leaving areas or regions of depression.
  • springs in the string is shaped to conform to the profile of the springs
  • Fig. 1 is a top plan view of a schematic representation
  • Fig. 2 is a side elevational view of the system
  • Fig. 3 is a view similar to Fig. 1 of a second presently
  • Fig. 4 is a side elevational view of the system
  • Fig. 5 is a perspective view of a string of pocketed coil
  • Fig. 6 is a cross-sectional view of an individual coil
  • Fig. 7 is a side elevational view of a string of pocketed
  • Fig. 8 is a partial perspective view of a weld head used
  • Fabric 1 6 preferably thermally weldable as is well known in

  • Each band 64 passes over spaced forward and trailing rollers 66, 68, at least one of which
  • supply roll 18 through the upstream stations and is advanced toward
  • the compressed springs 14 are permitted to relax and
  • the expansion of the springs 14 is controlled by a
  • Fig. 1 is generally parallel to the longitudinal
  • Each rotational member 72 includes a
  • rotational members 72 assist in advancing the springs 14 and fabric 1 6 toward a transverse seam forming station
  • the transverse seam forming station 78 forms a
  • transverse seam weld head 82 includes a transverse seam weld head 82 and a transverse seam weld head 82
  • transverse seam forming station 78 the fabric 1 6 between the
  • transverse seam 80 means for forming the transverse seam 80 such as stitching, staples
  • transverse seam 80 is formed, the fabric 1 6 is needed or gathered.
  • seam 54 formed at the free edges 28 of the fabric 1 6 is positioned
  • seam 80 is formed by the transverse seam forming station 78.
  • longitudinal seam 54 could be positioned prior to entering the
  • transverse seam forming station 78 even if it is not welded to the
  • seam 54 may be located anywhere between the top and bottom of the string although it is shown in the drawings as approximately in
  • a downstream or second transport station 94 preferably
  • transverse seam forming station 78 for discharge and subsequent
  • the transport mechanism could be embodied with wheels as in Figs.
  • transverse seam 80 may be positioned between the adjacent
