Blank feeder
 A blank feeder has a pair of guide rails for guiding blanks having a tubular form of square cross section to a bottom forming mandrel. The guide rails are formed with opposed recessed portions which are V-shaped in cross section for holding therebetween two corners of the blank on a diagonal thereof, and have shock absorbing means for mitigating the impact to be involved in the stiking contact of the blank with the guide rails.
