Abstract
Abstract Piece goods is extracted with exceptional effectiveness by passing the goods in web form over a transversely related suction slot at which air is delivered on the web from an aligned and oppositely disposed pressure slot at a velocity sufficient to strip moisture from the web.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
Piece goods extraction apparatus comprising means forming a stationary suction slot, traveling reticulate means for passing a moisture-containing piece goods web in spaced relation over said suction slot with the latter oriented transversely of and reaching fully across the web width and having a slot width proportioned for concentrating suction on said web through said traveling reticulate means, means forming an aligned pressure slot disposed opposite said suction slot and closely spaced at the other face of a passing piece goods web, means for impressing stripped moisture recovery suction at said suction slot, and means for delivering air at moisture stripping velocity through said pressure slot, said first and second mentioned means comprising, respectively, a stationary suction chamber and a surrounding openwork roll body of tubular form arranged for rotation, and said suction chamber presenting said suction slot in relation to the inner face of a piece goods web supported at the roll body surface and passed over said slot by roll rotation.
Claim 2
Dependent Claim
163 words
Piece goods extraction apparatus comprising means forming a stationary suction slot, traveling reticulate means for passing a moisture-containing piece goods web in spaced relation over said suction slot with the latter oriented transversely of and reaching fully across the web width and having a slot width proportioned for concentrating suction on said web through said traveling reticulate means, means forming an aligned pressure slot disposed opposite said suction slot and closely spaced at the other face of a passing piece goods web, means for impressing stripped moisture recovery suction at said suction slot, and means for delivering air at moisture stripping velocity through said pressure slot, said first and second mentioned means comprising, respectively, a stationary suction chamber and a surrounding openwork roll body of tubular form arranged for rotation, and said suction chamber presenting said suction slot in relation to the inner face of a piece goods web supported at the roll body surface and passed over said slot by roll rotation.
Claim 3
Dependent Claim
31 words
Piece goods extraction apparatus as defined in claim 1 wherein more than one suction slot and oppositely disposed pressure slot is provided for spaced operation in relation to a passing web.
Claim 4
Dependent Claim
48 words
Piece goods extraction apparatus as defined in claim 1 wherein said pressure slot is proportioned in width for allowing operation of said last mentioned means so that air delivered thereby through said slot is caused to have a velocity sufficiently high for effectively stripping moisture from said web.
Claim 5
Dependent Claim
19 words
Piece goods extraction apparatus as defined in claim 3 wherein said suction slot is wider than said pressure slot.
Claim 6
Dependent Claim
34 words
Piece goods extraction apparatus as defined in claim 4 wherein said suction impressing means is provided with operAting capability of an order sufficient for carrying off said delivered air together with moisture stripped thereby.
Claim 7
Independent Claim
133 words
The method of extracting moisture from a piece goods web which comprises causing said web to travel in spaced relation over a transversely related suction slot proportioned in width for concentrating suction on said web while delivering air under pressure on said web from an oppositely aligned and closely spaced pressure slot at a velocity sufficient to strip contained moisture from the web, said web being caused to travel while supported at the surface of an openwork roll body of tubular form that is arranged for rotation, and said suction slot being associated with a stationary suction chamber disposed within said roll body and presenting said suction slot in relation to the inner face of a piece goods web supported at the roll body surface and passed over said slot by roll rotation.
Claim 8
Independent Claim
133 words
The method of extracting moisture from a piece goods web which comprises causing said web to travel in spaced relation over a transversely related suction slot proportioned in width for concentrating suction on said web while delivering air under pressure on said web from an oppositely aligned and closely spaced pressure slot at a velocity sufficient to strip contained moisture from the web, said web being caused to travel while supported at the surface of an openwork roll body of tubular form that is arranged for rotation, and said suction slot being associated with a stationary suction chamber disposed within said roll body and presenting said suction slot in relation to the inner face of a piece goods web supported at the roll body surface and passed over said slot by roll rotation.
Claim 9
Dependent Claim
38 words
The method of extracting moisture from a piece goods web as defined in claim 6 wherein suction is impressed at said suction slot at a level sufficient for carrying off said delivered air together with moisture stripped thereby.
Claim 10
Dependent Claim
41 words
The method of extracting moisture from a piece goods web as defined in claim 6 wherein said web is caused to travel over more than one suction slot at which air is delivered under pressure from an oppositely aligned pressure slot.
