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.
Claims20
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;
- 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;
- and
- wherein the step of cooling the second device comprises transferring the thermal energy from the second device through a buffer material to the heat sink.

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 heat sink that is thermally coupled to the second device;
- providing a deformable buffer material intermediate the heat sink and the second device;
- and
- cooling the second device, during the transmitting vibrational energy step, by transferring thermal energy from the second device through the buffer material to the heat sink.
