Abstract
An idler rim is freely rotatably mounted adjacent the first closing ring of a bag closing device. In one embodiment, an idler rim is also placed on a pinch roller that engages the closing ring. These idler rims allow the package to be brought laterally more closely to the closing station so that the closure can be placed more tightly on the end of the package. There also is provided a bracket for mounting the entire bag closing device so that the closing device can be adjusted pivotally and linearly toward the conveyor.
