Abstract System for the production of steel-wire-reinforced flexible belts consisting at least of an elastomeric or synthetic-resin upper layer, a core in which the steel strands are embedded and a lower layer of such material bonded into a unitary laminate while the reinforcing strands are tensioned; the invention resides in the use of an equalizing press adapted to bond the core to the steel strands prior to the application of the upper and lower layers and the final laminating phase. A supply means for each of the outer layers is provided downstream of the equalizing press and the layer is, in turn, downstream of a further supply system adapted to sandwich the generally planar array of longitudinally extending tension steel strands between layers of the core material.
The improvement defined in claim 1 further comprising: prickle roller means between said first supply means and said equalizing press for at least partly perforating the core layer bonded to said array in said equalizing press; and degassing roller means between said second supply means and said laminating press for squeezing the laminate to expel any trapped gas therefrom prior to compression in said laminating press.
Claim 2
Dependent Claim
42 words
The improvement defined in claim 1 wherein said equalizing press has a width equal to a fraction of the length of said laminating press, further comprising means for movably supporting said equalizing press for movement in the major direction of the band.
Claim 3
Dependent Claim
31 words
The improvement defined in claim 3 wherein said for movably supporting said equalizing press means includes a common carriage for first supply means, said equalizing press and said second supply means.
