FIG. 4
TENSIONED UNROLLING DEVICE FOR FABRIC ROLLS The present invention relates to a fabric unrolling device.
Laminate systems such as those used as pond and ditch liners, roofing, roadbed paving and the like, are well known. in one such system, an asphaltic coating is applied to the surface to be coated, a sheet material is laid down over the asphaltic coating and a second asphaltic coating is applied over the sheet material.
The sheet materials commonly used in such laminate systems include woven fibrous fabric materials, woven wire mesh, felt paper, nonwoven polymeric fabric materials and the like. Such sheet materials are supplied in rolls of varying length and width. Of particular interest are nonwoven sheet materials formed from polypropylene fibers.
It is highly desirable that the sheet material be applied to the asphaltic undercoat uniformly and under at least a minimal longitudinal tension. Application of the sheet material leaves no room for error; it is virtually impossible to take it up and then reapply the material once it has been applied. The manual application methods presently in use are unsatisfactory. in one such method the roll of sheet material is placed over the asphaltic undercoat then unrolled while attempting to maintain proper unrolling alignment and, at the same time, keep the unrolled material under tension. In another method the' sheet material is unrolled, stretched tight and then laid in place. Obviously, neither method provides a uniform, tensioned application of the sheet material.
It is an object of this invention to provide an apparatus for unrolling fabric rolls under controlled tension. Other objects and advantages of this invention will be apparent from the following description and accompanying drawings, of which:
HO. 1 is an exploded view of a roll supporting unit;
HO. 2 is a side view showing the assembled braking means of a roll supporting unit;
FIG. 3 is an opposite side view of the braking means of a roll supporting unit showing the adjusting means therefor, and
FIG. 4 is a perspective illustrating the unrolling apparatus of this invention mounted on a pickup truck.
According to the present invention there is provided a roll supporting unit for use in unrolling rolls of fabric or other materials under controlled tension which comprises, in combination, a non-rotatable spindle adapted for mounting to a support means, a rotatable insert supported by the spindle and so adapted as to be inserted into the end of a roll core, and friction braking means in braking relation between the insert and the spindle to prevent free spinning of the insert and a roll of fabric supported thereby.
in another embodiment of this invention there is pro vided a roll mounting and dispensing device for use in unrolling fabric rolls under controlled tension which comprises, in combination, support means having demountably attached thereto a pair of roll supporting units so adapted as to be inserted in the opposite ends of the core ofa fabric roll.
A distinctive feature of this invention is that a roll support unit comprising braking means is used at each end of the fabric roll, thus allowing for independent control of the unrolling tension on each side of the fab- Referring now to the drawings, FIG. 1 shows a roll supporting unit which comprises a non-rotatable spindle 10 adapted for mounting to a support means, a rotatable insert 26 and friction braking means 38.
Spindle 10 includes a first end portion 12 and a second end portion 14. First end portion 12 is provided with means 16 to secure spindle 10 to a first support means, not shown, to prevent rotation of spindle 10 about such support means. First end portion 12 is further provided with a socket l8 perpendicular to the longitudinal axis of spindle l0 and so adapted as to receive an optional second support means. First end portion 12 is further provided with a radial flange 20 to which the non-rotatable portion of braking means 38 is secured. Second end portion 14 of spindle 10 has a smooth cylindrical outer surface for mounting insert 26 thereon for rotation thereabout. Second end portion 14 is generally of a slightly smaller diameter than first end portion 12 in order to provide a shoulder upon which rests bearing support 22, which is keyed to spindle 10 to prevent rotation thereabout. In association with hearing support 22 is a radial bearing 24 which, when the unit is assembled, acts to prevent longitudinal travel of insert 26 in the direction of first end portion 12.
Insert 26 includes a sleeve 28, having a smooth cylindrical inner surface, radial flange 30 and core engaging splines 32 so adapted as to be inserted into the end of a roll core. In the embodiment shown, flange 30 and splines 32 are welded to sleeve 28. Insert 22 is maintained in portion about spindle 10 by radial bearing 24 and retainer ring 34 which is mounted in groove 36 of spindle 10.
In another embodiment of this invention, insert 26 has an outer surface so adapted as to be engageable by the core of a fabric roll.
in yet another embodiment of this invention, the insert 26 has a tapered outer surface.
In a further embodiment of this invention, the insert 26 has a tapered outer surface having positioned thereon a plurality of longitudinal splines for gripping the roll core.
As shown in FIGS. 1 and 2, the braking means 38 includes a stationary backing plate 40 which is secured to flange 20 on spindle 10. Brake shoes 42 and 44 are supported by backing plate 40 and include linnings 46 and 48, rim portions 50 and 52 to which the linings are respectively attached and web portions 54 and 56 which support the rim portions. Fixed abutment 58 is attached to backing plate 40 and is engaged by the adjacent ends of brake shoes 42 and 44. Retaining spring 60 is secured to the webs 54 and 56 of brake shoes 42 and 44 respectively and holds the brake shoes in engagement with the fixed abutment 58.
The opposite adjacent ends of the webs 54 and 56 of brake shoes 42 and 44, respectively, engage expansion lug 62. Expansion lug 62 is pivotably supported by backing plate 40 and is attached to lever 64. Retracting spring 66 is secured to the webs of brake shoes 42 and 44 and holds the brake shoes in engagement with expansion lug 62.
The brake drum 68 is attached to radial flange 30 of insert 26.
In another embodiment of this invention, brake drum 68 can be secured, by suitable means, to sleeve 28 of insert 26, with splines 32 attached to the brake drum 68 and sleeve 28.
As shown in FIGS. l and 3, the braking forceof braking means 38 is adjusted by adjusting means which includes lever 64, coupling 70, threaded rod 72, rod guide 74, washing 76, spring 78 and adjusting knob 80. Rod guide 74 is pivotably supported by backing plate 40. Also included is an indicator 82 which provides some measure of the frictional braking force of brake shoes 42 and 44 against the inner braking surface of brake drum 68. Protective guard 84 generally surrounds the exposed portions of the adjusting means.
In a presently preferred embodiment a sleeve bearing material is interposed between the smooth outer surface of the second end portion 14 of spindle and the inner surface of sleeve 28 of insert 26.
in another embodiment of this invention, braking means 38 includes a radial braking element which is in braking relation with flange 30 of insert 26, a nonrotatable member which is in braking relation with the braking element and is adjustable longitudinally toward and away from insert 26 and adjusting means for applying a braking force to the adjustable member.
In FIG. 4, the unrolling device of the present invention is shown mounted on the front of a pickup truck. The truck-mounted device includes frame 86 which is generally adapted to mount the various components of the truck-mounted device, coupling means 88 and 90 for demountably coupling the unrolling device to the truck, roll supporting units 92 and support means 94, and brush units 96. Each of the various components is mounted to frame 86 by mounting means 98; only one such means 98 is indicated inasmuch as all such means are generally the same. Each mounting means 98 includes means for clamping mounting means 98 to frame 86. All such mounting means 98 are adjustable laterally.
In operation, a roll of fabric is positioned between roll supporting units 92. Sufficient fabric is unrolled to permit passage beneath brushes 96. The truck is moved forward until the end of the fabric is underneath the front wheels of the truck. The desired unrolling tension is set on each roll supporting unit. The truck then moves forward, unrolling the fabric under controlled tension. It is to be understood that the surface to which the laminate system is being applied has previously been coated with a suitable mastic, such as an asphalt. As the truck moves forward and the fabric unrolls under controlled tension, the fabric is brought into intimate contact with the mastic coating by brushes 96. One advantage of the present invention is that the tension on each end of the fabric roll is independently adjustable. By adjusting the tension so that there is a difference in tension at each end of the fabric roll, it is possible to lay the fabric in a curved path.
The unrolling device of the present invention can also be used in a hand-held mode by mounting an L- shaped handle in socket 18 of spindle II).
