CANADA LUMBERMAN AND WOODWORKER 37 Operators Should Choose Sanders Given the chance, operators will choose the most efficient sander, because an operator prefers the machine simplest to operate with drums easiest to cover. After thorough invest- igation he would like and recommend Berlin Triple Drum Sanders One operator may prefer the spiral type of drum, another the automatic take-up. He may choose either on the Berlin. SEND FOR SANDER BOOK The Berlin spiral drum is well known for its very effective sanding and polishing abilities. Paper is wound about it spirally with edges lapping so that there is no break in the cutting surface. A groove is made in the drum shell and covering to allow of lapping edges without a ridge. Under average conditions this drum is the most efficient built. The spiral drum does not depend upon automatic means to tighten the paper and keep all slack out of it. Many operators prefer to know just how tight their paper is. These men get better results with the spiral because they tighten the paper to suit themselves, after which no slack occurs. The Berlin automatic take-up straight rpening drum has no competitor in its own type, because of the flexibility of the take-up device. All other drums of this type use straight bars across the drum to clutch the paper, so that in order to take up slack in the paper it mu»t be loose all over. The Berlin flexible device takes up slack wherever it occurs in the length of the drum. No danger of paper folding over, creasing and tearing on this drum. Paper may be put on either of these Berlin drums as quick if not quicker than the less efficient drums offered by would-be imitators. Another thing—Berlin drums are balanced perfectly. The straight opening drum as well as the spiral is balanced in running condition and cannot be thrown out of balance. There's a 32-page booklet on B
