## Abstract

A feeding device (10) comprises: a support frame (12); an annular-shaped rotary frame (13); paired feeding rollers (15, 161) for nipping a strip-shaped member therebetween; a rotating motor (M1) for rotating the rotating frame (13); a feeding motor (M2) for rotating at least one (15) of the feeding rollers; and a driving force transmission mechanism (17) comprising a rotatable member relatively rotatable with respect to the rotating frame (13). The rotating frame (13) is rotated by driving of the rotating motor (M1) through a roller or a gear, and the at least one feeding roller (15) is rotated by the feeding motor (M2) through the driving force transmission mechanism (17), so that the strip-shaped member (100) is fed out in the form of a given helical configuration.

## Claims

### Claim 1

A feeding device for feeding out a strip-shaped member in the form of a helical configuration, comprising:
a support frame;
an annular-shaped rotary frame located on the side of an inner periphery of the support frame and supported in a rotatable manner;
paired feeding rollers supported with respect to the rotary frame and configured to nip the strip-shaped member therebetween;
a rotating motor installed to the support frame to rotate the rotary frame;
a feeding motor installed to the support frame to rotate at least one of the feeding rollers; and
a driving force transmission mechanism comprising a rotatable member relatively rotatable with respect to the rotary frame,
wherein
the feeding device is configured such that the rotary frame is rotated by driving of the rotating motor through a roller or a gear, and at least one of the feeding rollers is rotated by driving of the feeding motor through the driving force transmission mechanism.

### Claim 2 (depends on 1)

The feeding device as defined in claim 1, wherein the rotary frame is comprised of a plurality of segments which are separably coupled together, and the at least one feeding roller is detachably coupled to the rotary frame, whereby the strip-shaped member can be set in the nipped state.

### Claim 3 (depends on 1)

The feeding device as defined in claim 1, wherein the rotary frame is provided with a guide for guiding the strip-shaped member to the feeding rollers.

### Claim 4 (depends on 1)

The feeding device as defined in claim 1, wherein rotation of the feeding motor is transmitted to the rotatable member through at least one selected from the group consisting of a sprocket, a gear, a roller and a belt, to cause the rotatable member to be circulatingly moved along the rotary frame.

### Claim 5 (depends on 1)

The feeding device as defined in claim 1, wherein rotation of the rotatable member is transmitted to the at least one feeding roller through at least one selected from the group consisting of a sprocket, a gear, a roller and a belt, to cause the at least one feeding roller to be rotated.

### Claim 6 (depends on 1)

The feeding device as defined in claim 1, wherein the rotatable member is a chain or a belt.

### Claim 7 (depends on 1)

The feeding device as defined in claim 1, wherein the driving force transmission mechanism comprises: a drive sprocket configured to be rotated by the feeding motor; the rotatable member, wherein the rotatable member is configured to be circulatingly moved along the rotary frame according to rotation of the drive sprocket; a driven sprocket configured to be rotated by the rotatable member; a drive bevel gear configured to be rotated according to rotation of the driven sprocket; a driven bevel gear meshed with the drive bevel gear; and a rotary-shaft coupling configured to transmit rotation of the driven bevel gear to the at least one feeding roller.

### Claim 8 (depends on 1)

The feeding device as defined in claim 1, which further comprises a mount provided below the support frame, the mount having a traveling wheel.

### Claim 9 (depends on 1)

The feeding device as defined in claim 1, which further comprises a mount provided below the support frame, wherein the support frame is supported with respect to the mount in a swingable manner about a horizontal shaft.

### Claim 10

A method of feeding, to a pipe forming device, a strip-shaped member to be formed in a rehabilitation pipe, comprising the steps of:
preparing a plurality of strip-shaped member feeding devices each comprising: a support frame; an annular-shaped rotary frame located on the side of an inner periphery of the support frame and supported in a rotatable manner; paired feeding rollers supported with respect to the rotary frame and configured to nip the strip-shaped member therebetween; a rotating motor installed to the support frame to rotate the rotary frame; a feeding motor installed to the support frame to rotate at least one of the feeding rollers; and a driving force transmission mechanism comprising a rotatable member relatively rotatable with respect to the rotary frame, wherein the rotary frame is comprised of a plurality of segments which are separably coupled together, and the at least one feeding roller is detachably coupled to the rotary frame, whereby the strip-shaped member can be set in the nipped state;
installing the feeding devices in a rehabilitation pipe at a plurality of positions at intervals;
penetratingly inserting the strip-shaped member in the rotary frame after releasing the coupling of the segments thereof;
detaching the at least one feeding roller and nipping the strip-shaped member between the paired feeding rollers;
attaching the feeding rollers to one of the separated segments of the rotary frame and coupling the separated segments of the rotary frame together to form an annular shape; and
feeding out the strip-shaped member from one of the feeding devices toward a forward one of the remaining feeding devices or toward the pipe forming device, in the form of a helical configuration.
