Abstract
A method of manufacturing an insect coil includes the steps of feeding a sheet of dough material which includes an active insect control ingredient dispersed therein in a first direction, cutting the sheet of dough material with a die to form an insect coil, ejecting the insect coil from the die, and applying an extra dose of active to a specific location on the coil while the coil is being ejected from the die. Preferably, the extra dose of active is applied as a droplet using capillary forces that develop between the upper surface of the insect coil and the droplet itself and is forced through a tube located above the desired location. The insect coil may be tip treated only or may be zone treated at a plurality of spaced locations.
Claims8
A method of manufacturing at least two nested insect coils, comprising the steps of:
- providing a sheet of dough material comprising an insect coil composition, said dough material having an outer substantially planar upper surface;
- cutting said sheet of dough material with a die to form two nested insect coils, both of said insect coils having their own tip end;
- ejecting the nested insect coils from the die by moving an ejector between a non-ejecting position and an ejecting position;
- and
- applying a fluid mixture containing an active insect control ingredient to the respective tip ends of the insect coils while said coils are being ejected from said die, wherein the step of applying said fluid mixture comprises dispensing, as said ejector initially begins to eject said nested coils, a discreet amount of said fluid mixture to dosing ports disposed closely spaced above the outer upper surface so that said discreet amount of said fluid mixture touches said outer substantially planar upper surface and as the ejector then continues to eject the nested coils from the die in a direction away from said dosing ports capillary forces between said outer substantially planar upper surface and said fluid mixture at said dosing ports draw the discreet amount of said fluid mixture from said dosing ports onto the outer substantially planar upper surface to form a droplet on both of the respective tip ends of both of the coils, while not applying said fluid mixture on top of at least some other portions of said outer upper surface of the coils.
