1. An apparatus comprising:
a die body including a cavity, the cavity having an opening on a dispensing side thereof; and
one or more movable components disposed on the dispensing side of the die body and outside of the opening of the cavity of the die body to define at least a portion of a dispensing slot adjacent to and substantially parallel to the opening of the cavity,
wherein the one or more movable components are movable with respect to the opening of the die body to allow a width of the dispensing slot along a cross direction to be dynamically adjustable,
wherein at least one of the one or more movable components includes an abutting surface to define the dispensing slot, and a shim is attached to the abutting surface and movable along with the at least one of the one or more movable components back and forth along the cross direction, the shim is positioned to be substantially parallel to the opening of the cavity of the die body such that when the shim moves, the shim at least partially blocks the opening of the cavity to dynamically adjust the width of the dispensing slot.
