Title (EN) A FOLDER
(FR) CHEMISE
Abstract: front page image
(EN)A folder for use in the transport of an original sheet (25) and a copy sheet (26), engaged with each other, past the heat radiator in a thermocopying machine has a cover sheet (22) of thermally and mechanically resistant plastics foil which is permeable to infra-red rays. To reduce the amount of heat transferred to the copying material by convection, the cover sheet as an irregular surface. The irregularities (23, 24) are produced by a subsequent treatment of smooth plastics foil. An irregular surface may optionally be imparted to the carrier sheet (21) of the folder as well to reduce the contact area with the surrounding parts and thus the transfer of heat by convection.
(FR)Une chemise pour le transport d"une feuille originale (25) et d"une copie (26), engagees l"une avec l"autre, passant devant un radiateur thermique d"une machine de thermo-copiage possede une feuille de couverture (22) en un materiau plastique de resistance thermique et mecanique qui est permeable aux rayons infrarouges. Pour reduire la quantite de chaleur transferee sur le materiau de reproduction par convection, la feuille de couverture possede une surface irreguliere. Les irregularites (23, 24) sont produites par un traitement ulterieur de la feuille de plastique lisse. Une surface irreguliere peut eventuellement etre formee sur la feuille porteuse (21) de la chemise egalement pour reduire la surface de contact avec les parties environnantes et par consequent reduire le transfert de chaleur par convection.
