An Affixing Machine is a machine that affixes postage stamps to an envelope, postcard or wrapper. Affixing machines first appeared in the 1850s but were not widely used until the early 20th century. There were also much larger floor models produced for this purpose. Stamp affixing machines were brought about by the need to mechanically affix stamps for bulk processing of mail. A secondary reason for the machines was to make the theft of stamps more difficult for employees with access to large inventory of coils.
