Abstract
Abstract Relatively inflexible travelling webs, such as carpets or rugs having a coating on the reverse side thereof, are guided in a convoluted path around a plurality of guide rollers, and in this path they are heated by being subjected to steam heat, hot air heat, heat-producing radiation or heat derived from other sources.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
221 words
In an apparatus for printing relatively inelastic textile webs whose longitudinal edges are required to travel in a predetermined path through a printing station, a combination comprising textile web supplying means; driven roller means for pulling the web off from the supply means and for forwarding said web to said printing station with said longitudinal edges in position to travel in said predetermined path; retarding roller means upstream of said driven roller means for retarding the web so that the web is subjected to longitudinal tensioning intermediate said driven roller means and said retarding roller means; edge feeler means located between said driven roller means and said retarding roller means for sensing whether one edge of the web deviates from said predetermined path; means mounting said supply means movable in a direction transverse to the longitudinal direction of said path and cooperating said feeler means for shifting said supply means in said transverse direction when said edge feeler means senses deviation of said one edge from said predetermined path, to thus return said edge to said predetermined path; and heating means for heating the web along a major portion thereof between said driven roller means and said retarding roller means to enhance the stretchability of said portion of said web to avoid fold formation during lateral shifting of said supply means.

Claim 3
Dependent Claim
18 words
A combination as defined in claim 1, wherein said heating means comprises a device for discharging hot steam.
Claim 4
Dependent Claim
18 words
A combination as defined in claim 1, wherein said heating means comprises a device for discharging saturated steam.
Claim 5
Dependent Claim
18 words
A combination as defined in claim 1, wherein said heating means comprises a device for discharging hot air.
Claim 6
Dependent Claim
15 words
A combination as defined in claim 1, wherein said heating means comprises infra-red radiating means.
Claim 7
Dependent Claim
15 words
A combination as defined in claim 1, wherein said heating means comprises short-wave radiating means.
Claim 8
Dependent Claim
15 words
A combination as defined in claim 1, wherein said heating means comprises a gas-burning heater.
Claim 9
Dependent Claim
26 words
A combination as defined in claim 1, and including a housing enclosing said major portion of said web, said heating means being located in said housing.
Claim 10
Dependent Claim
39 words
A combination as defined in claim 8, wherein said web supply means is a reel, and said mounting means is a carriage movable in said transverse direction, said reel and said retarding roller means being mounted on said carriage.
Claim 11
Dependent Claim
103 words
A combination as defined in claim 9, wherein said housing is an elongated substantially vertically extending housing, said driven roller means being mounted in an upper portion of said housing, and including a reversing roller on said carriage, a first guide roller mounted in said housing for rotation about a fixed axis adjacent to said driven roller means, a second guide roller in a lower portion in said housing, said web being successively guided from said reversing roller over said first guide roller and said second guide roller to said driven roller means to leave said housing downstream of said driven roller means.
Claim 12
Dependent Claim
93 words
A combination as defined in claim 8, and including storage means downstream of said housing, said storage means including a plurality of upper guide rolls mounted for rotation about fixed parallel axes spaced normal to the longitudinal direction of their axes from each other, and a plurality of lower guide rollers connected transversely spaced from each other to each other for movement in vertical direction and having axes parallel to those of the upper guide rollers for guiding the web between said driven roll means and the printing apparatus along a zig-zag path.
Claim 13
Independent Claim
103 words
A method for forwarding a relatively inelastic textile web from a web supply toward a printing station at which the longitudinal edges of the web are required to travel along a predetermined path, comprising the steps of moving the web in longitudinal direction under tension from the supply means along said predetermined path towards said printing station; moving the supply means in a direction transverse to said longitudinal direction if the web deviates from said predetermined path; and heating a major portion of the tensioned web to enhance its stretchability to avoid fold formation during movement of the web in said transverse direction.
