Abstract
Apparatus for dispensing a plurality of string members, in particular thread or filaments coated with hot melt adhesives, to a machine wherein the string members are applied to a moving web. The apparatus includes a device for simultaneously regulating the tension on each of the string members. In the preferred embodiment, the tension regulating device includes a pair of cylindrical rollers disposed transverse to the direction of string member travel and about which the string members are wrapped. A braking mechanism is included to provide controlled resistance to the rotation of the cylindrical rollers and thereby regulate the tension on the string members.
