Cookie depending on drying conditions and local basis weight distribution

The number of cockles and their distribution are highly dependent on drying rate and the local basis weight distribution. As the applied drying temper ature increases, cockling increases on the paper strip. Although the total basis weight is a key factor deciding the amount of cockling, the local bas is weighs distribution is an another factor in deciding the cockle distribu tion. Most paper breaks take place on the cockle location during tensile te sting, Paper deforms quite uniformly at the beginning of drying and deforms nonuniformly at the end of drying. The number of cockles and their locatio n can be decided by the combined effect of the paper environment and the pa per itself.
