Abstract
A light detector is supported in a mask box which extends into the cavity accommodating the looptaker with an edge of the surface adjacent the looptaker and upstream to the air currents generated by the looptaker closer to the looptaker than an edge downstream in order to discourage lint build up on the adjacent surface. A light source is fashioned with a lens projecting into the cavity accommodating the looptaker similarly to discourage lint build up.
