Abstract:
1. Apparatus for forming coils of tubing and securing tubing in the coil comprising: a first template having a spiral trough therein and; a second template adjacent the first template having a spiral trough therein which is the mirror image of the first spiral trough, such that when the first and second templates are adjacent the troughs form a spiral tunnel in the templates, such that a tube inserted therein will form a coil with the tubes adjacent, a means for moving the templates together and apart, at least one tab cavity in the first template adjacent the coil of tubes for applying a material across one side of the coil such that the material extends from a tangent line where the tubes engage each other in the coil to approximately the top of the tubes thus filling in the space between the tubes with material, a port in the first template fluidly connected to the tab cavity to supply material to the tab cavity.
