Abstract
Abstract A device for sensing wet tire cord fabric treated with a liquid bonding agent carried by a vaporizable solvent. The device is characterized by a chamber in which solvent vapor is accumulated. The chamber is formed between a pair of rotatable metal rolls which engage fabric moving past them. A conventional gas analyzer is coupled to the chamber for drawing fluid from the chamber and making an analysis of the fluid to determine if the fabric is still wet and has not been sufficiently dried.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
158 words
An apparatus for sensing wetness of supposedly dry fabric treated with a vaporizalbe solvent carrier and coating agent, comprising: a. a pair of parallel, elongated idler rolls for contacting a moving, supposedly dry fabric and carrying vapor from the fabric into a chamber in which the vapor accumulates; aa. means for mounting the idler rolls for contacting the same side of the fabric and for rotating freely about axes which are parallel to the moving fabric and transverse to the direction in which the fabric moves past the idler rolls; b. means for forming adjacent the fabric a confined chamber, in which vapor from wet fabric can accumulate, the chamber designed to at least partially include the idler rolls; and c. means for drawing from the chamber, vapor accumulating therein, said means including a conduit for carrying vapor away from the chamber; and cc. gas analyzer means connected to the conduit for detecting vapor drawn from the chamber.
Claim 2
Independent Claim
158 words
An apparatus for sensing wetness of supposedly dry fabric treated with a vaporizalbe solvent carrier and coating agent, comprising: a. a pair of parallel, elongated idler rolls for contacting a moving, supposedly dry fabric and carrying vapor from the fabric into a chamber in which the vapor accumulates; aa. means for mounting the idler rolls for contacting the same side of the fabric and for rotating freely about axes which are parallel to the moving fabric and transverse to the direction in which the fabric moves past the idler rolls; b. means for forming adjacent the fabric a confined chamber, in which vapor from wet fabric can accumulate, the chamber designed to at least partially include the idler rolls; and c. means for drawing from the chamber, vapor accumulating therein, said means including a conduit for carrying vapor away from the chamber; and cc. gas analyzer means connected to the conduit for detecting vapor drawn from the chamber.
Claim 3
Dependent Claim
89 words
The apparatus of claim 1, wherein the chamber-forming means includes: d. a pair of partition walls disposed in spaced relation between the idler rolls, each of the walls including oppositely curved semi-circular edges configured to match the cylindrical shape of the idler rolls, the walls being closely spaced to the idler rolls and moving fabric; and e. a cover plate secured to the edges of the partition walls farthest from the moving fabric and covering the chamber formed by the partition walls, idler rolls, moving fabric, and cover plate.
Claim 4
Dependent Claim
18 words
The apparatus of claim 2, wherein the cylindrical surface of each idler roll contacting the fabric, is metallic.
Claim 5
Independent Claim
168 words
An apparatus for sensing wetness of supposedly dry fabric treated with a vaporizable solvent carrier and coating agent, comprising: a. a confined chamber with an opening through which vapor can enter and accumulate in the chamber; b. means for guiding a supposedly dry fabric past the opening of the chamber; c. at least one idler roll for carrying vapor from the fabric into the chamber; d. means for mounting the roll for contacting the fabric moving past the chamber and for rotating freely about an axis which is parallel to the moving fabric and transverse to the direction in which the fabric moves past the roll; e. means for positioning the roll for carrying vapor from the fabric through the opening of the chamber for accumulation in the chamber; and f. means for drawing from the chamber, vapor accumulating therein, said means including a conduit for carrying vapor away from the chamber; and ff. gas analyzer means connected to the conduit for detecting vapor drawn from the chamber.
Claim 6
Independent Claim
168 words
An apparatus for sensing wetness of supposedly dry fabric treated with a vaporizable solvent carrier and coating agent, comprising: a. a confined chamber with an opening through which vapor can enter and accumulate in the chamber; b. means for guiding a supposedly dry fabric past the opening of the chamber; c. at least one idler roll for carrying vapor from the fabric into the chamber; d. means for mounting the roll for contacting the fabric moving past the chamber and for rotating freely about an axis which is parallel to the moving fabric and transverse to the direction in which the fabric moves past the roll; e. means for positioning the roll for carrying vapor from the fabric through the opening of the chamber for accumulation in the chamber; and f. means for drawing from the chamber, vapor accumulating therein, said means including a conduit for carrying vapor away from the chamber; and ff. gas analyzer means connected to the conduit for detecting vapor drawn from the chamber.
Claim 7
Dependent Claim
136 words
The device of claim 4, wherein the chamber includes: g. a second idler roll spaced from said at least one roll and contacting the same side of the fabric as said at least one roll, the second roll being mounted for rotating freely about an axis which parallels the rotational axis of said at least one roll; h. a pair of partition walls disposed in spaced relation between the idler rolls, each of the walls including oppositely curved semi-circular edges configured to match the cylindrical shape of the idler rolls, the walls being closely spaced to the idler rolls and moving fabric; and i. a cover plate secured to the edges of the partition walls farthest from the moving fabric and covering the chamber formed by the partition walls, idler rolls, moving fabric, and cover plate.
Claim 8
Dependent Claim
55 words
The device of claim 5 including in sequence, means for coating the fabric with a liquid; means for removing excess liquid coating from the fabric; and means for drying the fabric; said coating means, removing means, and drying means being located upsteam of the wetness testing structure with respect to the direction of fabric travel.
Claim 9
Dependent Claim
28 words
The device of claim 6, wherein the means for removing excessive liquid coating from the fabric includes a pair of scraper blades for compressively engaging fabric moving therebetween.
Claim 10
Dependent Claim
31 words
The device of claim 7, which includes means associated with the apparatus for adjusting the position of the scraper blades when the gas analyzer indicates the fabric is not sufficiently dried.
