A preferred embodiment of the invention provides tube cutting apparatus including, a head structure mounting cutter means defining a cutting station for a length of tubular material, an elongate rod-like structure for mounting the tubular material, tube engaging means for advancement of said tubular material along said rod-like structure to said cutting station, support means for said rod-like structure including a portion of table-like form, means for an initially free pivotal connection of said table-like support portion to said head structure and a pedestal type support for the opposite end of said table-like support portion including means for a lateral adjustment thereof about said pivot means to effect a precise alignment of said rod-like structure with said cutting station.
The embodiment has means defining a loading station for placement of said tubular material in connection with said tube engaging means, means for driving said engaging means along said rod-like structure, and means for energizing said driving means to produce an automatic placement of said tube engaging means at said loading station. The driving means has, in operative connection therewith, means to then effect a retraction of said tube engaging means from said loading station to a position defining a starting station. Means are provided to energize said driving means to move said tube engaging means and the tubular material engaged thereby in the direction of said cutting station an exact amount of travel in accordance with the segment to be cut from said tubular material and there are further means to sense an energized condition of said driving means and to prevent the operation of said cutting means until said driving means is fully deenergized.
