temple (loom part); tenter
A device on a loom that keeps the cloth stretched to the correct width during weaving. Technical term used in textile contexts.
The temple on the loom keeps the cloth width constant.
Rarely used kanji form.
The derivation is uncertain; the kanji 伸 (stretch) and 子 (small thing) suggest a stretching device, but this is a conventional association rather than a confirmed historical origin.
