lõõside

Lõõsid is a Latvian term that translates to "bellows" in English. Bellows are an air-compressing device that consists of a flexible bag or chamber, typically made of leather or rubber, which is expanded and then contracted to force air out through a nozzle. Historically, bellows were a crucial tool in various crafts and industries, most notably in metallurgy and blacksmithing.

The primary function of bellows is to provide a continuous stream of air, which is essential for stoking fires. In blacksmithing, this increased airflow is used to raise the temperature of a forge to a level sufficient for heating and shaping metal. The expanding and contracting action of the bellows creates a draft that intensifies the combustion process. Early bellows were often simple, hand-operated devices, while later designs incorporated mechanical linkages or even water power for more consistent and powerful airflow.

Beyond blacksmithing, bellows have found applications in other areas. They were used in pipe organs to supply air to the pipes, in pharmacies for dispensing powders, and in certain types of firearms for cleaning and maintenance. The effectiveness of bellows lies in their ability to deliver a concentrated burst of air, making them indispensable for tasks requiring controlled and intensified heat or air movement. While modern technology has introduced more sophisticated air-moving devices, the fundamental principle of the bellows remains relevant in understanding the history of many industrial and artisanal processes.
