Abstract
A convective warmer for flexible plastic bags containing foam precursor chemicals includes an outer housing and an inner enclosure supported within the housing, the inner enclosure having foraminous floor and ceiling plates and foraminous dividers which divide the inner enclosure into vertical compartments for containing vertical stacks of bags. An air space exists between the housing and the inner enclosure, and a forced-air heater is arranged to heat air within the air space and circulate the heated air from the air space, through the foraminous floor plate into the compartments, and out the foraminous ceiling plate back into the air space. A loading door provides access to upper portions of the compartments for loading bags into the warmer, and a dispensing door provides access to lower portions of the compartments for removing a bottommost bag from a stack of bags in the warmer.
