1. In an apparatus for dispensing elongated material from a roll, a system for regulating the tension in the material, comprising:
- guide means for defining the path the elongated material is to follow, said guide means including at least one guide member movable in response to increased tension in the material to shorten the path thereof and movable in response to decreased tension in the material to lengthen the path thereof and movable in response to decreased tension in the material to lengthen the path thereof;
active brake means for applying a braking force to the roll;
a pivoted lever coupling the movable guide member to the active brake means;
said pivoted lever and active brake means cooperating to reduce the braking force when the movable guide member moves to shorten the aforesaid path length and to increase the braking force when the movable guide member moves to lengthen the aforesaid path length;
a second roll, the first and second rolls being mounted on first and second spindles, respectively; and
mechanical, non-adhesive linkage means for linking the elongated material on the first roll to the elongated material on the second roll so that when the first roll is depleted of material, the second roll can immediately begin supplying material in its stead.

Abstract
A tape dispenser includes an automatic tension control mechanism and provision for auto-splicing the tail portion of one tape to the leading portion of another. The tensioning mechanism includes a brake band that extends at least partially about a tape spindle and is tensioned in response to the position of a spring-biased tensioning roller over which the tape is routed.

12. In a tape dispensing apparatus, an improvement comprising:
-
first and second spools of tape, the tape on each of said spools having a leading end and a trail end; and an element on the trailing end of the first tape that cooperates with an element on the leading end of the second tape to make said second spool of tape self splicing to the first so that when the first spool becomes depleted of tape, the second spool can begin immediately dispensing tape in its stead. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. In a tape dispensing apparatus that includes two spools of tape, an apparatus for applying a variable but equal braking force to each of said spools comprising:
-
first and second spindles to which the spools can be mounted; first and second anchor points fixed at positions adjacent the first and second spindles, respectively; a spring having first and second ends, the first end being connected to the first anchor point; a brake band having a first end connected to the second anchor point and a second end connected to the second end of the spring, the brake band extending at least partially around and in engagement with the first and second spindles; and a control member coupled to the second end of the spring for controlling the tension therein.
