Abstract
Methods and apparatuses for manufacturing portions of absorbent articles may include or facilitate conveying a substrate through a nip formed between a first device and a second device, transmitting vibrational energy from the second device toward the first device via the nip to alter the substrate, and cooling the second device by transferring thermal energy from the second device.
Claims21
A method of manufacturing portions of absorbent articles comprising:
- conveying a substrate through a nip formed between a first device and a second device;
- transmitting vibrational energy from the second device toward the first device via the nip to alter the substrate;
- providing a projection extending from the second device, wherein the projection is in thermal communication with the second device, and wherein the projection is positioned proximate to a working surface of the second device;
- providing insulation on at least part of the second device to reduce condensation, frost, and/or ice accumulation;
- cooling the second device by transferring thermal energy from the second device to the projection;
- and
- conveying a chilled fluid over the projection to cool the projection.
