Abstract
A batcher has a brake (E) connected to the packing roll (B) for slowing the packing roll as during an unwinding phase to vary the packing ratio between the packing roll (B) and the drive roll (A). A drive mechanism (D) utilizes a single drive clutch for imparting a free wheeling action to the packing roll during unwinding so as to facilitate operation of the brake in effecting the proper packing ratio.

Apparatus for driving a surface winder having a drive roll and a packing roll for taking up and letting off a web from a web roll wound upon a roll core comprising:
- a motor driving said drive roll for taking up a web upon said web roll;
- means driving said packing roll;
- a friction brake;
- and
- means connecting said friction brake to said packing roll for varying the packing ratio between the drive roll and the packing roll.
Apparatus for driving a surface winder having a drive roll and a packing roll for taking up and letting off a web from a web roll wound upon a roll core comprising:
- a motor driving said drive roll for taking up a web upon said web roll;
- means driving said packing roll;
- means including a friction brake varying the speed of the packing roll for varying a packing ratio between the drive roll and the packing roll;
- and
- means controlling said means varying the speed of the packing roll varying the packing ratio between the drive roll and the packing roll when letting off said web wherein the packing roll is driven at a speed less than that of the drive roll.
A method of driving a surface winder having a drive roll and a packing roll for taking up and letting off a web from a web roll wound upon a roll core comprising the steps of:
- providing a motor driving said drive roll for taking up a web upon said web roll;
- and means driving said packing roll from said drive roll;
- applying a retrading force exerting a braking action upon the packing roll for varying a packing ratio between the drive roll and the packing roll;
- and
- controlling said braking action varying the speed of the packing roll for varying the packing ratio between the drive roll and the packing roll when letting off said web.
