Dependent claims

An applier apparatus for applying a sheet of flexible material to a cylindrical body comprising:

a support frame having two parallel support rails;
a conveyor table having a conveyor belt for conveying the sheet in a first direction, wherein the conveyor belt has a plurality of rollers, wherein each roller is rotatably mounted on an outer conveyor belt surface, wherein the plurality of rollers each rotate about an axis parallel to the first direction;
said conveyor table further comprising a plurality of support legs, each support leg having an outer leg portion and a respective inner leg portion, wherein each outer leg portion is slidable over its respective inner leg portion so that each support leg can expand or contract in length whereby the conveyor table can tilt, wherein each support leg is slidably mounted to one of the support rails, wherein each outer leg portion is connected to a respective nut which is connected to a respective spindle which is rotatably mounted in a longitudinally-fixed manner to the inner leg portion associated with the outer leg portion in question.
