Abstract
Abstract An improved method for making three- or four-way taper pillows from a web of soft compressible material that is folded into a batt and encased in a pillow tick. This is accomplished by folding the web along first fold lines to produce a multi-ply web having a plurality of superimposed plies located between opposite edges while positioning some of the fold lines between the opposite edges such that there are a greater number of plies along the center of the multi-ply web then at the opposite edges and subsequently folding the multi-ply web along second fold lines extending perpendicular to the opposite sides of the multiply web to produce a pillow batt having a plurality of layers each having a plurality of plies. The batt is then enclosed in a pillowed tick by compressing the peripheral edge to produce a completed pillow. In one embodiment, a three-way tapered pillow is produced by locating all of the fold lines along one edge of the layers in a common plane while the fold lines along the opposite edge are staggered relative to each other and in an alternative embodiment a four-way taper is produced by staggering the fold lines of the layers along both edges.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
141 words
A method of making a rectangular pillow batt comprising the steps of moving a web of compressible material in one direction; folding said web at a first station to produce a multi-ply web having a plurality of plies with the fold lines along opposite edges of said multi-ply being staggered relative to each other; moving said multi-ply web in a second direction perpendicular to said first direction and folding said multi-ply web along spaced fold lines substantially normal to the previous fold lines to produce a batt having a plurality of superimposed layers with the fold Lines of said layers along one edge being staggered relative to each other to produce a batt having a maximum thickness at the central portion and tapering to a reduced thickness towards at least three edges when said batt is encased in a pillow tick.
Claim 2
Independent Claim
141 words
A method of making a rectangular pillow batt comprising the steps of moving a web of compressible material in one direction; folding said web at a first station to produce a multi-ply web having a plurality of plies with the fold lines along opposite edges of said multi-ply being staggered relative to each other; moving said multi-ply web in a second direction perpendicular to said first direction and folding said multi-ply web along spaced fold lines substantially normal to the previous fold lines to produce a batt having a plurality of superimposed layers with the fold Lines of said layers along one edge being staggered relative to each other to produce a batt having a maximum thickness at the central portion and tapering to a reduced thickness towards at least three edges when said batt is encased in a pillow tick.
Claim 3
Dependent Claim
33 words
A method as defined in claim 1, including the further step of arranging all of the fold lines of the layers in a substantially common plane along a fourth edge of said batt.
Claim 4
Dependent Claim
23 words
A method as defined in claim 1, including the further step of staggering the fold lines along a fourth edge of said batt.
Claim 5
Dependent Claim
79 words
A method as defined in claim 1, including the step of feeding said web through a guide mechanism located above the conveyor; reciprocating said guide mechanism between extreme position above said conveyor; selectively reversing the direction of movement of said mechanism intermediate said extreme positions; and depositing said web on a conveyor moving in a second direction to locate some of the fold lines of the plies of the multi-ply web intermediate the extreme positions of the reciprocating mechanism.
Claim 6
Dependent Claim
56 words
A method as defined in claim 4, including the step of guiding said multi-ply web through a second guide mechanism; reciprocating said second guide mechanism between extreme positions defining opposite edges of said batt; and selectively reversing the second guide means at locations intermediate said extreme positions to produce some fold lines spaced from said edges.
Claim 7
Dependent Claim
20 words
A method as defined in claim 4, including the step of compressing said web before it is folded into layers.
Claim 8
Dependent Claim
22 words
A method as defined in claim 5, including the step of intermittently severing said web to produce a plurality of individual batts.
Claim 9
Dependent Claim
44 words
A method as defined in claim 1, including the step of enclosing said batt in a pillow tick to compress said batt and produce a pillow having a maximum thickness at the central portion tapering to a reduced thickness towards at least three edges.
Claim 10
Independent Claim
89 words
A method of producing a pillow batt which comprises folding a compressible fibrous web of material along spaced fold lines to produce a multi-ply web having a plurality of superimposed plies located between opposite edges; positioning said plies such that there are a greater number of plies along the center of said multi-ply web than at opposite edges; and folding said multi-ply web along fold lines extending between said edges to produce a pillow batt having a plurality of layers each having a plurality of plies of a web.
Claim 11
Independent Claim
89 words
A method of producing a pillow batt which comprises folding a compressible fibrous web of material along spaced fold lines to produce a multi-ply web having a plurality of superimposed plies located between opposite edges; positioning said plies such that there are a greater number of plies along the center of said multi-ply web than at opposite edges; and folding said multi-ply web along fold lines extending between said edges to produce a pillow batt having a plurality of layers each having a plurality of plies of a web.
Claim 12
Dependent Claim
78 words
A method as defined in claim 9, in which said web is folded in a manner that the opposed edges of said multi-ply web define opposed edges of said batt and at least some of the fold lines of said multi-ply web define a second pair of opposed edges for said batt, the further step of positioning at least some of said fold lines of said layers at a location spaced from said second pair of opposed edges.
Claim 13
Dependent Claim
30 words
A method as defined in claim 10, in which all of the fold lines along one of said second pair of edges are located in a substantially common vertical plane.
