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.
Claims14
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;
- and
- contact cooling the second device, during the transmitting vibrational energy step, by transferring thermal energy from the second device to a heat sink that is substantially isolated from the vibrational energy;
- wherein the heat sink is in contact with the second device, and wherein the heat sink has a coefficient of friction in the range of about 0.05 to about 0.4.
