Abstract (en)
A belt (1) for a shoe press with felt side resin layer (3) grooves (5) having improved crack resistance in the vicinity of a shoe edge has the grooves (5) in that vicinity of a reduced depth, increased pitch or both. In a first embodiment, the depth (b') of the recessed grooves (55) in the portion of the felt side resin layer outside of the width of a paper sheet to be made, i.e., the outside grooves, is shallower than the depth (b) of the recessed grooves (5u) in the portion of the layer which is inside of the width of the paper sheet, i.e., the inside grooves. In a second embodiment, the depth of the outside grooves (5s) diminishes stepwise toward the outside from the edge of the paper. In a third embodiment, the pitch (c'), or widthwise spacing, of the outside grooves is greater than the pitch (c) of the inside grooves and each outside groove is one-half of the depth of the inside grooves. In a fourth embodiment, the outside grooves are of both increased pitch and stepwise diminishing depth. <IMAGE>
