Abstract:
1. A device for processing hydrous polymer gel of variable thickness, comprising: a first cutting roll having at least one axially extending cross cutting element including a cutting edge; and a back-up roll spaced from said cutting roll so as to form a nip, whereby said at least one cutting edge cooperates with said back up roll to cut a layer of hydrous polymer gel at the nip; said first cutting roll being mounted above the rotational axis of said back-up roll such that a smallest distance between said cutting edge of the at least one cross cutting element and said back-up roll is situated below and upstream of a crown of the back-up roll with respect to a substantially linear conveying path of the layer of hydrous polymer gel as it approaches the nip, wherein when said cutting edge is positioned at said smallest distance, said cutting edge is positioned below and upstream of said crown, and wherein said cutting edge of said first cutting roll is a continuous cutting edge to completely separate a downstream portion of the hydrous polymer gel from the remainder of the hydrous polymer gel.
