Abstract
Abstract Apparatus for forming a loop in a web path has a flexible sheet formed as an endless band placed in the web''s path. A source of pressure air is encircled by the sheet and when air is blown from the source directly against the sheet, the sheet is urged against the web to form a loop in the web.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
115 words
Apparatus for forming a loop in a web within a web handling apparatus, said loop forming apparatus comprising: a flexible sheet having a curvilinear portion disposed adjacent a path of said web, said sheet forming a closed loop having a web engaging outer side, means for fixing a portion of said flexible sheet to a stationary element of said web handling apparatus so that the closed loop formed by said sheet is movable about the fixed portion thereof, and means for blowing air directly onto an internal side of said sheet within said closed loop and for thereby urging said curvilinear portion of said sheet against said web to form a loop in said web.
Claim 2
Dependent Claim
115 words
Apparatus for forming a loop in a web within a web handling apparatus, said loop forming apparatus comprising: a flexible sheet having a curvilinear portion disposed adjacent a path of said web, said sheet forming a closed loop having a web engaging outer side, means for fixing a portion of said flexible sheet to a stationary element of said web handling apparatus so that the closed loop formed by said sheet is movable about the fixed portion thereof, and means for blowing air directly onto an internal side of said sheet within said closed loop and for thereby urging said curvilinear portion of said sheet against said web to form a loop in said web.
Claim 3
Dependent Claim
12 words
Apparatus as in claim 1 wherein said sheet comprises an endless band.
Claim 4
Dependent Claim
21 words
Apparatus as in claim 2 wherein said sheet at least partially surrounds said means for blowing air directly onto said sheet.
Claim 5
Dependent Claim
55 words
Apparatus as in claim 3 wherein said means for blowing air directly onto said sheet comprises a tube at least partially surrounded by said sheet, means for supplying pressure air to said tube, and said tube having apertures disposed to direct pressure air directly onto a side of said sheet opposite said web engaging side.
Claim 6
Dependent Claim
46 words
Apparatus as in claim 1 wherein the pressure of air blown onto said sheet is sufficient to form said sheet and said web into a loop, but is slight enough to allow said sheet to move against said pressure due to web tension along said loop.
Claim 7
Dependent Claim
20 words
Apparatus as in claim 1 wherein said web comprises a web remnant supporting therein a plurality of partially precut labels.
Claim 8
Dependent Claim
14 words
Apparatus as in claim 6 wherein said web remnant surrounds each of said labels.
Claim 9
Dependent Claim
28 words
Apparatus as in claim 6 wherein said web remnant is disposed along generally opposite edges of said labels and wherein said labels are contiguous within said web remnant.
Claim 10
Dependent Claim
26 words
Apparatus as in claim 1 including guide means engaging said sheet for forming said sheet into a desired loop shape upon application of pressure air thereto.
Claim 11
Dependent Claim
58 words
Loop forming apparatus as in claim 1 wherein said means for blowing air includes a tube extending at least partially into said closed loop of said flexible sheet, said tube having an air passage therethrough and apertures connected to the passage and disposed to direct air onto said internal side of said sheet opposite said web engaging side.
Claim 12
Dependent Claim
43 words
Loop forming apparatus as in claim 1 wherein said flexible sheet has two ends joined to each other to form said closed loop, said closed loop being fixed to said stationary portion of said web handling apparatus at the juncture of said ends.
