Abstract
An apparatus for imparting a braking force to an advancing strand is disclosed, and which includes a mechanical compensating arm brake followed in series by a movement dependent brake. The movement dependent brake may take any one of several forms, including an eddy-current brake which is directly connected to a roll which is driven by the strand, a hysteresis brake which is directly connected to a roll which is driven by the strand, or a brake of any type which is connected to a roll which is driven by the strand via a clutch, such as a centrifugal clutch, which is operated as a function of the speed of the movement of the strand.
Claims13
An apparatus for imparting a braking force to an advancing strand and comprising
- first braking means for imparting a brake force to the advancing strand which is controlled as a function of the tension of the advancing strand, and
- magnetically actuated second braking means for imparting a braking force to the advancing strand which is controlled as a function to the movement of the advancing strand, said second braking means comprising a rotatable roll about which the advancing strand is adapted to be wound, a speed controlled clutch having a drive end connected to said roll and an opposite non-drive end, and a movement controlled braking means connected to the non-drive end of said clutch.
An apparatus for imparting a braking force to an advancing strand and comprising
- a rotatable supply spool adapted to have the strand wound thereupon,
- first braking means for imparting a braking force to the advancing strand as it is unwound from said supply spool and which is controlled as a function of the tension of the advancing strand, and
- magnetically actuated second braking means positioned downstream of said first braking means for imparting a braking force to the advancing strand which is controlled as a function of the movement of the advancing strand, said second braking means comprising a roll about which the advancing strand is adapted to be wound, a speed controlled clutch having a drive end connected to said roll and an opposite non-drive end, and a movement controlled braking means connected to the non-drive end of said clutch.
