Abstract

An apparatus for making cable including an elongate core and a surrounding longitudinally welded tube includes one or more pairs of opposing tube forming rolls which form a tape into a generally tubular shape surrounding the advancing core. A pair of tube forming rolls define exit tube forming rolls mounted to have an adjustable spacing therebetween. A first sensor generates an exit roll spacing signal which is one parameter that may be displayed to the operator or used to directly to control the spacing. Downstream from an induction welding coil, a pair of opposing weld rolls are mounted to have an adjustable spacing therebetween for permitting setting of a desired pressure between the heated opposing longitudinal edges of the advancing tape. A second sensor generates a weld roll spacing signal which may also be displayed or used to directly control the spacing within a desired range. An associated method is also disclosed.
