What is it called?
\nThis device is known in French as an \u201c\u00c9carteur de t\u00e9tine de trayeuse\u201d\u2014best translated as a milking machine teat cup liner expander (also described as a liner flaring\/rolling tool).<\/p>\n
Where it was used
\nIt belonged to dairy farming operations and was used during milking on the cow\u2019s udders (the teats\/trayons) to help fit the milking equipment correctly and safely.<\/p>\n

\nWhy it existed (the problem it solved)
\nIn the early period of mechanical milking (\u201cpots \u00e0 traire\u201d era), the rubber liner (manchon) that wrapped around the teat was not pre-molded. Because the liner was inserted into a stainless-steel tube, farmers needed to roll\/flare the liner\u2019s edge so it would sit properly on the tube and avoid hurting the udder.<\/p>\n
Main purpose and function<\/p>\n
Primary function: Expand\/roll (\u201crebouler\u201d) the end of the rubber liner on the metal tube.
\nKey benefit: Reduce the risk of pinching or injuring the cow\u2019s udder while ensuring a secure, consistent fit.
\nPractical advantage: It was faster and easier than using fingers, especially when done repeatedly.
\nHow it was typically used (simple steps)<\/p>\n
Insert the rubber liner into the stainless tube of the teat cup assembly.
\nPlace the tool at the liner\u2019s end.
\nOperate the mechanism to flare\/roll the liner edge into position.
\nConfirm the edge is smooth so it won\u2019t rub or cut the udder.
\nWhen it was common<\/p>\n
It was used before liners were factory pre-molded, meaning early-to-mid 20th century in many dairies that relied on older milking systems.
\nThe text specifically notes that after World War II, liners became pre-molded, reducing the need for this tool.
\nWhy it disappeared<\/p>\n
Farmers had to do the rolling step often, because liners were removed after each milking to be cleaned in hot water.
\nAfter WWII, manufacturers introduced pre-molded liners, so the rolling\/expanding task was no longer necessary.
\nAs a result, these tools became obsolete and were often discarded or scrapped.
