Abstract
In a packaging line adapted to feed articles into a packer and including lane guides defining lanes for columns of articles fed under line pressure to the packer, the lane guides are provided with an offset portion adapted to create a back pressure for reducing the line pressure at the packer. The offset portion provides sufficient resistance to the flow of articles so that the articles entering the packer are more readily accommodated, particularly articles of the type which are compressed by excessive line pressures and tend to upset the operation of the packer as a result of excessive or varying line pressure. The reduced line pressure permits operation of standard packing equipment for the handling of relatively soft and compressable cylindrical plastic bottles.
