# Manufacture of strings and catgut

Manufacturing by white-collar men and women of strings and catgut (=medical suturing material for operations) at the N.V. Eerste Nederlandsche Snaaren en Catgutfabriek-Hakkert in Rotterdam. The following are dealt with in succession: processing the base material, i.e. sheep intestines, which are cleaned and checked for porosity and split; removing any traces of fat from the intestines; twisting into strings and drying; grinding and cylindricalizing; sterilizing; drying, sorting and wrapping the strings; laboratory analysis of the strings; packing the sterile end-product in glass ampoules; application in an operating theatre.

Not offered: its uploader or archive marks it public domain, and nothing the site holds bears that out (its record gives no year, or a year from 1978 on, which no US term has left), so where it is free is not known. Unclear is not offered.
