An open mesh is adapted for use as the upper portion of a cubicle curtain. The open mesh has a major portion with openings, and a narrow and a wide selvedge. The open mesh major portion has said integral narrow knitted selvedge on an edge opposed to said integral wide knitted selvedge. The selvedges have a substantially finer mesh than the open mesh major portion. The open mesh is knitted in multiple adjoining panels. Adjoining panels are connected with in order a first narrow selvedge, an intermediate strip comprising a tear thread, a waste strip and an open mesh relief band, and a second narrow selvedge. The selvedges are thus made integral with the major open cell portion and are ready without further manufacturing steps (except for separating from a roll and for sizing) for the insertion of grommets in the wide selvedge and the sewing to a vision-resistant fabric at the narrow selvedge with the narrow selvedge retaining a straight outer edge due to use of the relief band during sizing on a pin frame.
A cubicle curtain having a main lower portion of vision-resistant fabric, and an upper open mesh portion, said open mesh having a major portion with openings, said open mesh major portion having an integral knitted upper wide selvedge on one edge thereof, said knitted wide selvedge having a substantially finer mesh than said open mesh major portion, and said open mesh major portion having an integral narrow knitted selvedge on an other edge thereof, said narrow selvedge having a substantially finer mesh than said open mesh major portion, and said narrow selvedge having a straight outer edge.
An open mesh, adapted for use as the upper portion of a cubicle curtain, said open mesh having a major portion with openings, said open mesh major portion having an integral knitted upper wide selvedge on one edge thereof, said knitted wide selvedge having a substantially finer mesh than said open mesh major portion, and said open mesh major portion having an integral narrow knitted selvedge on an opposed edge thereof, said narrow selvedge having a substantially finer mesh than said open mesh major portion, and said narrow selvedge having a straight outer edge.
An integrally knitted plurality of panels in adjoining side-by side relationship, each said panel being an open mesh, adapted for use as the upper portion of a cubicle curtain, said open mesh having a major portion with openings, said open mesh major portion having an integral knitted upper wide selvedge on one edge thereof, said knitted wide selvedge having a substantially finer mesh than said open mesh major portion, and said open mesh major portion having an integral narrow knitted selvedge on an opposed edge thereof, said narrow selvedge having a substantially finer mesh than said open mesh major portion, an intermediate strip between said adjoining panels, a said narrow selvedge on each side of said intermediate strip, said intermediate strip comprising a tear thread, a waste strip and an open mesh relief band.
The method of making the open mesh portion of a cubicle curtain comprising the steps of integrally knitting a plurality of panels in adjoining side-by side relationship, each said panel being an open mesh, said open mesh having a major portion with openings, said open mesh major portion having an integral knitted upper wide selvedge on one edge thereof, said knitted wide selvedge having a substantially finer mesh than said open mesh major portion, and said open mesh major portion having an integral narrow knitted selvedge on an opposed edge thereof, said narrow selvedge having a substantially finer mesh than said open mesh major portion, with an intermediate strip between said adjoining panels, a said narrow selvedge on each side of said intermediate strip, said intermediate strip comprising a tear thread, a waste strip and an open mesh relief band, mounting said panels on a pin frame for finishing, then making a separation of one of said narrow selvedges at said tear thread, and making a final separation of said intermediate strip from said other said narrow selvedge.
