Abstract
Indiarubber sheet is simultaneously perforated and patterned by means of dies or drums, one carrying pins and the other having corresponding recesses, one or both having a relief pattern thereon. The surface of the matrix roll may be of vulcanized rubber, the recesses being formed on running the apparatus while the rubber compound is still soft. The rolls may be heated to effect partial or complete vulcanization of the sheet, or this may be carried out as a separate operation. Specification 457,203 is referred to.
