Abstract
Abstract The apparatus comprises a turntable plate arranged on a platform (1), there being tube means (6) mounted on the plate such as to form a conical shape with the aid of a bolted joint (7). To one side of the turntable plate (3) there are arranged on the platform three rollers (12,13,14) and on another part thereof there is arranged a feed roller (29) and guide rolls (31,32). The roller (29) and guide rolls (31,32) are adjustable in two planes in relation to the platform (1). For winding up a boom it is taken between the rolls (31,32) over the feed roller (29) and over the rollers (12,13,14), where the expansion means are flattened so that the boom is wound up in a flattened condition on the tube means (6) forming the conically shaped winding bobin.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
135 words
Apparatus in reeling up booms, including so-called self expanding booms, comprising: a vertically oriented winding means driven by a motor, the winding means being arranged for winding thereon of said boom in a flattened condition, first means defining at least one first roller oriented substantially parallel to the winding means and located upstream of and laterally adjacent to the winding means for cooperating in flattening the boom for winding on the winding means, and feed means defining a feed roller located upstream of said first roller (1) for guiding the boom during the winding operation and (2) for applying a braking force to the boom sufficient to press the boom against said first roller and thereby obtain said flattened condition of the boom as the boom is supplied to the winding means for winding thereon.
Claim 2
Dependent Claim
135 words
Apparatus in reeling up booms, including so-called self expanding booms, comprising: a vertically oriented winding means driven by a motor, the winding means being arranged for winding thereon of said boom in a flattened condition, first means defining at least one first roller oriented substantially parallel to the winding means and located upstream of and laterally adjacent to the winding means for cooperating in flattening the boom for winding on the winding means, and feed means defining a feed roller located upstream of said first roller (1) for guiding the boom during the winding operation and (2) for applying a braking force to the boom sufficient to press the boom against said first roller and thereby obtain said flattened condition of the boom as the boom is supplied to the winding means for winding thereon.
Claim 3
Dependent Claim
51 words
Apparatus as claimed in claim 1, wherein the feed roller is mounted in a structure actuable for adjusting the orientation of the feed roller in two planes at right angles to each other, said structure including two guide rolls having their shafts at right angles to that of said feed roller.
Claim 4
Dependent Claim
86 words
Apparatus as claimed in claim 1 in which the path of the boom runs over the feed roller and then through an acute angle around said first roller and then onto said winding means, the first roller being spaced from said winding means sufficient to closely clear the boom when fully wound on said winding means, said first roller and feed roller being spaced from each other along a line which is generally tangential to the winding means and to a boom substantially fully wound thereon.
Claim 5
Dependent Claim
49 words
Apparatus as claimed in claim 3 in which said first means comprises several said first rollers closely spaced to each other along the perimeter of said winding means along the path of the boom and located remote from said feed roller and the rotational axis of said winding means.
Claim 6
Dependent Claim
177 words
Apparatus in reeling up booms, including so-called self expanding booms, comprising a vertically arranged winding means suitably driven by a motor, the boom being arranged for winding onto said winding means in a flattened condition, one or more first rollers arranged substantially parallel to the winding means for coaction with the boom and arranged laterally in relation to the winding means, and a feed roller adapted for guiding the boom during the winding operation and for applying a braking force, as necessary, for pressing the boom into a compressed condition around said first rollers, the feed roller being mounted in a structure for adjustment of the feed roller in two planes at right angles to each other, said structure carrying the feed roller including two guide rolls having their shafts at right angles to that of the feed roller, the structure carrying the feed roller and guide rolls being attached to a second disc mounted on a central shaft, which in turn is attached to a first disc movably attached to a platform carrying said winding means.
Claim 7
Dependent Claim
177 words
Apparatus in reeling up booms, including so-called self expanding booms, comprising a vertically arranged winding means suitably driven by a motor, the boom being arranged for winding onto said winding means in a flattened condition, one or more first rollers arranged substantially parallel to the winding means for coaction with the boom and arranged laterally in relation to the winding means, and a feed roller adapted for guiding the boom during the winding operation and for applying a braking force, as necessary, for pressing the boom into a compressed condition around said first rollers, the feed roller being mounted in a structure for adjustment of the feed roller in two planes at right angles to each other, said structure carrying the feed roller including two guide rolls having their shafts at right angles to that of the feed roller, the structure carrying the feed roller and guide rolls being attached to a second disc mounted on a central shaft, which in turn is attached to a first disc movably attached to a platform carrying said winding means.
Claim 8
Dependent Claim
29 words
Apparatus as claimed in claim 5, wherein both discs can be locked in different mutual angular positions, by a locking pin going through mutually registering holes in the discs.
Claim 9
Dependent Claim
50 words
Apparatus as claimed in claim 5, wherein the first disc is pivotably mounted to the platform with the aid of a shaft extending substantially parallel to the plane of the platform, there being means arranged between the platform and first disc for adjustment in the height of the first disc.
Claim 10
Dependent Claim
