Abstract 1. In tire building apparatus having tire casing rotating means for rotating a tire casing in its plane, having ribbon applying means for applying an elastomeric ribbon to said casing as its is rotated and having mounting means for one of said rotating and applying means for rotating said one means around an axis substantially parallel to said plane, the combination therewith of second rotating means and programming means for controlling the azimuth position of said one means with respect to said axis, said second rotating means comprising reversible driving means connected to said mounting means for rotating said mounting means and hence, said one means, around said axis, and control means connected to said driving means for controlling the movement thereof, and said programming means comprising a plurality of spaced camming members engageable with said control means for actuating the latter and thereby causing movement of said driving means, moving means connected to at least one of said programming means and control means for producing relative movement in two transverse directions between said control means and said camming members for engaging successive ones of said camming members with said control means and stepping means operable by one of said casing rotating means, said applying means and said tire casing as said ribbon is applied to said casing and connected to said moving means for causing said relative movement as predetermined lengths of said ribbon are applied to said casing.
