Patent number: 8727259Abstract: A self-compensating tension control device for regulating the withdrawal of filamentary material from a spool includes a fixed support that maintains an inverted cam surface and a spindle assembly rotatably carrying the spool. A tension force applied to the filamentary material, in opposition to a biasing force, moves the spindle assembly linearly in relation to the fixed support. A braking mechanism includes a brake drum rotatable with the spindle assembly, a friction band adapted to engage the brake drum and a rocker arm that engages the cam surface. When the tension force applied to the filamentary material is reduced and unable to overcome the biasing force, the cam roller engages the cam surface and causes the friction band to generate a braking force on the brake drum. Withdrawal of the filamentary material at a regular rate occurs when the biasing force is balanced with the tension force.Type: GrantFiled: February 9, 2011Date of Patent: May 20, 2014Assignee: RJS CorporationInventor: Raymond J Slezak

Patent number: 8500056Abstract: A self-compensating tension control device for regulating the payout of filamentary material from a spool includes a fixed support and a spindle assembly rotatably carrying the spool. A tension force applied to the filamentary material, in opposition to a biasing force, moves the spindle assembly linearly in relation to the fixed support. An eddy current braking system includes a conductive member rotatable with the spindle assembly and a magnetic member carried by the fixed support. The spindle assembly and the conductive member move linearly toward a side-by-side relationship with the magnetic member when the tension force applied to the filamentary material is reduced and unable to overcome the biasing force. Linear movement of the spindle assembly and the associated conductive member can be obtained by either a straight line mechanism or a linear ball bushing mechanism. A supplemental brake may also be used.Type: GrantFiled: October 1, 2010Date of Patent: August 6, 2013Assignee: RJS CorporationInventor: Raymond J. Slezak

Patent number: 6435445Abstract: A self-compensating tension control device for regulating the payout of filamentary material from a spool includes a fixed support and a spindle assembly pivotably mounted to the fixed support, wherein the spindle assembly rotatably carries the spool of filamentary material. A pull-off force imparted by the filamentary material causes angular movement of the spindle assembly and rotation of the spool. A braking assembly mounted to the fixed support and coupled to the spindle assembly applies a braking force corresponding to an angular position of the spindle assembly.Type: GrantFiled: June 27, 2000Date of Patent: August 20, 2002Assignee: RJS CorporationInventor: Raymond J.

Patent number: 6098910Abstract: A tension control device (10) for regulating the payout of filamentary material (24) from a spool (22) includes a fixed support (12, 14), a swing frame assembly (16) pivotably mounted on the fixed support and predisposed to a holding position, and a spindle assembly (20) carried by the swing frame assembly. The spindle assembly (20) carries the spool (22) and rotates with the spool as the filament is pulled off the spool. A braking assembly (18) is pivotably mounted on the fixed support (14) and is movable with the swing frame assembly (16). A cam (30) is fixably mounted on the fixed support and bears against the braking assembly (18) and forces the braking assembly to control the rotation of the spindle assembly. A pull-off force applied by filamentary material causes the swing frame assembly to move away from the holding position and allows rotation of the spindle assembly.Type: GrantFiled: September 11, 1998Date of Patent: August 8, 2000Assignee: Wayne-Dalton Corp.Inventor: Raymond J.

Patent number: 6010089Abstract: A tension control device (10 for tensioning filamentary material (F) being withdrawn from a spool (24) including, a mounting support (11), a spindle (24) receiving the spool and rotatably mounted relative to the mounting support, a control arm (13) rotatably mounted on a shaft (15) in operative relation to the spindle, a brake element (18) mounted on the control arm for selectively retarding rotation of the spindle, a guide roller (16) rotatably attached to the control arm over which the filamentary material being withdrawn from the spool is passed, and a break-away mounted (80) of the guide roller to provide tension relief when the tension in the filamentary material exceeds a predetermined value. A break-away signaling system (95) detects and signals angular movement of the guide roller relative to the control arm.Type: GrantFiled: September 11, 1998Date of Patent: January 4, 2000Assignee: RJS CorporationInventors: Charles J.
