(57) Designed to carry out a method of transferring the ornamental designs produced on
a tubular bag or transfer pattern, within which the section to be decorated is accommodated,
a vacuum being applied to the said bag during a phase of heat treatment within an
oven, comprising an oven in which two laterally adjacent chambers (1-1') are provided,
equipped with respective seatings (6) and (7) which enter the oven in its lower region
and which project substantially therefrom, to an extent corresponding to the length
of the sections, each seating being intended to receive a frame (8-9) from a pair
of auxiliary tables (10) and (11) on which the loading and unloading of the said sections
(16), with their corresponding bags (17), takes place, to which bags the vacuum is
applied by coupling their ends to two guides (18) through which vacuum tubes (20)
pass, on which vacuum tubes sealing sleeves (19) and opening/closing keys (21) are
mounted, the vacuum tubes (20) initially being connected to vacuum pumps (12) and
(13) situated on the tables (10) and (11), and subsequently being connected to vacuum
pumps (14) and (15) situated on the seatings (6) and (7).
