Abstract
Abstract of the Disclosure A roller conveyor for carrying a running length of untensioned tire building strip material is provided with roller elements which rotate about axes displaced at smaller angler relative to the general direction of movement of the strip so that the strip being conveyed is urged into contact with a fixed guide. The arrange-ment is improved by substituting for conventional rollers cylindrical brushes having radially extending bristles sufficiently stiff to support the strip satisfactorily and as well to yield axially of the brush so as to limit the force applied to urge the strip against the guide.
The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Description
The present invention relates to conveying9 and par-ticularly to conveying a running length of tire making material in web or strip form while steering the same to a predetermlned lateral alignment with respect to a given reference llne.
Broadly~ the in~ention comprises~ in an apparatus for conveying a t~re building component ln a desired direction which apparatus includes a longitudinal frame~ a plurality of rotatable carrylng elements supported on the frame and cooperable to form a com-ponent carrying surface~ the improvement wherein the elements comprise brushes of cylindrical form rotatable about axes~ said axes being parallel to each other and disposed ang~larly with respect to the desired direction.
The invention is found to be particularly useful - in the delivery to a tire building machine of components such as chafer stock and/or shoulder pad stock for building a tire These components are formed~ normally~ of ~ -- uncured rubber~ being of natural and/or synthetic rubber and compounds thereof without filamentary;reinforcement materials. The in~ention~ however~ can flnd application as well in web materials ~or building tires which in-clude filamentar~ rein~orcement materials.
A preferred embodiment of the invention illustrating the best mode now contemplated for the practice thereof will be described hereinbelow with reference to the attached drawings forming a part of the present specifica-tion and in which drawings:

~5~7~i~3 Fig. l is a plan ~iew of an apparatus according to the lnvention;
Fig. 2 is a partial cross-section in elevation taken as indicated by the line 2-2 in Fig l;
Fig. 3 is a vièw of a conveying ~nd guidlng element of the apparatus of Fig. 1 oriented as indicated by the line 2-2 in Fig. l;
Figs~ ~ and 5 illustrate alternative embodiments of the element illustrated in Fig. 3.
Making reference to Figo l~ a rw~ning length strip S
of tire building material is illustrated as baing conveyed by the apparatus lO from its receiving end 12 to its delivery end l~o It will be appreciated that the apparatus 10 illustrated in Fig. 1 pre~erably is one of a pair of conveyors arranged symmetrically with respect to a .:
plane 15 coincident with or parallel to the mid-circumferential plane o~ a tire building drum (not . .
- shown) me conveyors~ being identical except as to hand~ are represented and described by the apparatus lO.
As the strip is moved forward by the apparatus lO
it is progressively displaced laterally from its path upon entering the apparatus at 12 to a new alignment with respect to a given reference line 16 before the strip leaves the apparatus at 14 as may be seen in the figure. The preferred alignment of the strip S as it leaves the apparatus 10 ~s de~ined by a gentle abutment ~ -2-.
i ~ S7 ~ ~ 3 of the edge S' with a flxed guide 18 forming a part of the apparatus 10. ~:.
me reference line 16, and in the apparatus 10, the guide 18~ can be positioned to suit the requirements of the succeeding operation on the strip. For example~
the guide 18 can be located in a plane normal to the axis of the tire building drum and at a selected distance from the mid-circumferential plane of such drum whereby the strip is delivered to the building drum at its intended location~ axially of the tire being built~
Making reference also to Fig. 2~ the strip is - conveyed forYard, in the direction of its own length~
as well as urged gently toward the alignment guide 18.
by a plurality of rotatable carrying elements 20 which ~ .
are rotatably supported in the frame 22 and cooperate to form a supporting surface. m e conveying elements comprise brushes of cylindrical form each rotatable about its own cylindrical axis 2~. The axes 24 of the several ~ rotatable elements 20 are parallel to each other These : ~ 20 axes are angularly adjustable with respect to the guide ;~
member 18. me apparatus 10 provides for ad~ustment of the angles of the respective axes from about 89 degrees to about 80 degrees with respect to the guide member.
` The degree o~ angularity of the axes controls the rate of lateral mo~ement of the strip. In building tires~
it is particularly important that the strip materials not be distorted and it is thus desirable that the strip S not be urged laterally so forcefully as to crowd it .:
: against the guide.

In accordance with the lnvention~ therefore~ the :
rota-table carrying elements 20 comprise brushes of cylindrical form in which a nmltiplicity of bunches of fiber bristles 21 are fixed in and extend radially 5 from a central core 23 which is mounted on a shaft 25 for rotation about the axis 24, In this way the carrying elements are provided with a soft elastically resilient surface which satisfactorily supports the running length strip S~ tends to carry the strip in a direction normal to the axis 2~ of the carrying element and yet is so yieldable as to prevent the exertlon of an ~ndue lateral thrust on the strip being carried thereon~
The apparatus illustrated in Fig, 1 comprises the rigid rectangular frame 22 comprising a pair of spaced .
parallel structural angles 31 and a parallel pair of end bars 33 connecting the respective ends of the structural angles, : .
The frame 22 includes a bar 35 of rectangular cross~
section fixed to and extending along one of the i:
structural angles 31 to accommodate a plurality of bearings 37 siaced therealong, ~: :
The frame 22 is carried on a parallel pair of cross rails 40 affixed to a suitable support structure l~2 so that the frame and a strip carried thereon can be disposed : .

~ 6 ~ 3 drum~ a parallel pair of traverse screws 44 are rotatably supported on the support structure tu co-operate with the threaded bushings 46 which are non-rotatably fixed to the frame so that the frame is moved laterally in response to rotation of the screws. The two traverse screws are corotatab7y connected by a chain 48 drivingly engaging the sprockets 49 co-rotatably fixed on the respective screws. The lateral adjustment of the position of the frame i5 e*fected by a crank 51 or the like engaged with the crank stub 53 on one of the traverse scre~s.
Rotation of the rotatable elements 20 is effected by a plurality of stub shafts 54 mounted rotatably in the bearings 37 and connected by the flexible couplings 56 to the shafts 25 of the respective elements. The stub shafts ~4 are corotatably connected by an endless chain 58 engaging each of the respective sprockets 60 corotatably mounted on the stub shafts 54, The stub shaft 54'~also aarries a sprocket 62 which is connected by a chain 64 to a sprocket 66 mounted corotatably on and laterally slidable along a drive shaft 68 which is mounted rotatably in a bearing 70 fixed to the support structure~ The drive sprocket 72 corotatably fixed on the shaft 68 is connected to drive means (not shown) which is drivable in timed relation with a tire bul}ding drum to which the strip is carried, ' : :
