A bottom heater 10 for use in assembling a container bottom 304 and a sleeve 302 includes a body having a peripheral wall 14 and a heated air passage 38 terminating in an outlet 18 in the peripheral wall. A shape of at least a portion of the peripheral wall defining the outlet is such that heated air exiting the outlet is fluidly attached to an adjacent portion of the peripheral wall after exit because of the Coanda effect. The container forming machine comprises a mandrel 204 forming a surface 216 for supporting at least a portion of the sleeve and terminating in a first end 218 for supporting at least a portion of the container bottom relative to the sleeve. The bottom heater is movable relative to the mandrel to position the outlet relative to the sleeve and the container bottom. The mandrel can include a vacuum conduit 220 for maintaining the cup bottom in position on the mandrel. |
