Abstract

A machine for continuously forming heat-reflective blanks is provided. The heat-reflective blanks each include a blank of sheet material and a thermal film patch coupled to the blank. The machine includes an intake station configured to align a first blank of sheet material and a second blank of sheet material for application of a first thermal film patch and a second thermal film patch, respectively. The intake station is further configured to maintain a spacing between the first blank and the second blank. The intake station includes adjustable hold-down bars for maintaining an alignment and the spacing of the first and second blanks. The machine also includes an applicator station configured to apply the first and second thermal film patches to the first and second blanks, respectively, to form a first heat-reflective blank and a second heat-reflective blank, and an ejection station configured to eject the heat-reflective blanks.

Dependent claims

A method for forming a heat-reflective blank including a blank of sheet material and a thermal film patch coupled to the blank, said method comprising:

transferring the blank from a hopper to a transport system, the transport system including a plurality of lugs spaced apart along a first conveyor;
spacing the blank from at least one adjacent blank in a non-overlying relationship along the first conveyor by contacting a trailing edge of the blank with one or more of the plurality of lugs, wherein the spacing exposes an interior surface of the blank including an interior surface of a panel configured to receive the thermal film patch;
transporting the blank using the transport system while the blank is subject to an applied force that maintains the blank in a planar configuration and in the non-overlying relationship;
applying glue to at least one of the blank and the thermal film patch;
positioning the thermal film patch to a predetermined location on the interior surface of the panel configured to receive the thermal film patch;
and
applying the thermal film patch to the blank in the predetermined location on the interior surface of the panel to form the heat-reflective blank, the thermal film patch being adhered to the blank by the applied glue.

transferring a first blank of sheet material and a second blank of sheet material from a hopper to a transport system, the transport system including a plurality of lugs spaced apart along a spacing conveyor;
aligning the first blank and the second blank in a spaced, non-overlying relationship by contacting a trailing edge of the first blank with a first pair of the plurality of lugs, wherein the aligning exposes an interior surface of the first blank including an interior surface of a first panel configured to receive a first thermal film patch and an interior surface of the second blank including an interior surface of a second panel configured to receive a second film patch;
transporting the first and second blanks using the transport system while the first and second blanks are subject to an applied force that maintains the first and second blanks in a planar configuration;
and
applying the first and second thermal film patches to the interior surface of the first and second panels of the first and second blanks, respectively, to form a first heat-reflective blank and a second heat-reflective blank.
