A system for dispensing hot melt adhesives, comprising an adhesive dispenser including a fluid passage leading to an outlet. The system further comprises a supply conduit fluidly connected to the fluid passage and a feeding mechanism configured to feed an elongate, flexible element of solid adhesive into the supply conduit. The system further comprises a first heating element positioned along at least a portion of the supply conduit to melt a portion of the elongate, flexible element being fed into the supply conduit and thereby form a supply of liquid adhesive within the supply conduit.

Unwinding systems and methods are provided for unwinding a fiber from a bobbin. The unwinding system can include an axle defining a first axis extending an axial direction, a bobbin rotatably mounted around the axle, a pulley positioned to receive the fiber from the bobbin, wherein the pulley is rotatable around a second axis, and a sensor positioned between the bobbin and the pulley. The bobbin is moveable along the axial direction, and wherein the fiber extends tangentially from a surface of the bobbin.

A rotary spool spinner for wire dispensing that includes: a plurality of wire dispensers, where said wire dispensers are secured onto a vertical post, wherein each dispenser includes a flat circular plate that is mounted onto a support bracket secured with a nut; a guide aligned with each dispenser, where each guide is supported within framing between support posts; top stabilizing rods attached to the vertical posts and support posts creating frame support; and a base, where the base is supported on wheels and said base is attached to the vertical posts and support posts. The wire dispenser may be secured to the vertical post by a swing arm with a pin. The support bracket preferably includes a spring-loaded clutch.
