Positive weft regulator for loom in region of fluted roller - with reduced number of change gears in multi-step gear mechanism

摘要

Positive weft regulator in the form of a multi-step gear mechanism for loom in region of fluted roller comprises a septuple gear stage which meshes with a gear roller and which is mounted loosely on a shaft allowing it as desired to mesh with the septuple gear stage above it be means of an intermediate gear. The intermediate gear is suspended in a frame which is mounted loosely on a shfat and can be connected to the septuple gear stages by sliding displacement. The second septuple gear stage is mounted fixedly on its shaft. Instead of a number of different change gears for the different weft densitities, no spare change gears need to be kept in stock. By changing only one gear, 49 different weft densities can be obtd.
