the corrugating machine, show marked breaks incontinuity at the joints, which further impair the quality ofthe finished product.
Felt or conventional fabrics are also relatively heavy andtherefore difficult to assemble onto the machine; the weight,combined with a high friction coefficient, of such materialsincreases the energy consumption of the machine; andfinally, not being very permeable, felt or conventional fabrics not only impair dispersion of the steam issuing from thecardboard, but also
