The wet cloth was stretched and dried on a tenter rack. Wooden
frames were built outside the mill but near to it , to prevent
valuable cloths being stolen.
Blunt headed nails were driven
at intervals into the frames and the selvedges of the cloth
were pulled evenly and hooked onto the nails. Hence the expression
being on tenter hooks!
On Tenter Hooks
A Tenter Hook
From 1727 until 1770, all cloths
were measured by inspectors and ‘sealed’.
After mechanisation,
a tenter machine was used to dry the cloth. It also removed creases
and straightened the fabric. The cloth was still stretched to
the correct width on tenter hooks.
