Title: Printing pad for reproducing several copies - formed by soaking fibre mat with copying soln. exposing and developing to produce non-absorbent regions
Inventor: DOTZEL KLAUS-PETER DIPL ING
IPC: G03F7/12
Filed: 1973-09-19
Abstract: A fibre (e.g. PVC, polyethylene, polypropylene, polyamide, polyester, etc) mat is impregnated with a copying soln (e.g. chromo-gelatin, sensitised polyvinyl alcohol, polymethane, unsatd polyester, polyamide) and then irradiated with imaged light to form a latent image in the copying soln. extending completely through the mat. The latent image is then developed to render region of the mat nonabsorbent to printing fluid, so that when printing fluid is applied to the mat, and the mat is pressed against a printing sheet a copy of the image is reproduced. The fibres in the regions not used for printing may be rendered nonabsorbent to oil or water depending on the printing ink used. The printing pads can be used in a flat state or attached to a roller to produce repetitive copies.

Title: Tubular packaging skins of polyethylene terephthalate - biaxially oriented in two stages without secondary inflation
Inventor: STRUTZEL HANS
IPC: B29C48/10
Filed: 1973-08-30
Abstract: A tubular thin wall film made from polyethylene terephthalate (I) oriented in two stages, specifically a biaxial orientation stage followed by longitudinal orientation, has a tensile strength of 40-60 kp/mm2 and tear strength of 40-70 kp/mm2 in the longitudinal direction plus elongation to break of 350-800% in transverse direction. Suitable packaging skins have external dia. of 10-150 mm, wall thickness of 15-50 mym and reversion of 90 degrees C of 5, pref. about 2% in transverse direction. The first stage biaxial orientation is effected at a temp. in the region of the 2nd order transition of the matl. viz 84-86 degrees C and the longitudinal orientation at a temp. between the 2nd order transition and the m. pt. pref. in the range 148-152 degrees C. During 1st stage, the longitudinal orientation should be between 3.3:1 and 3.3:1-3.7:1 and the transverse orientation between 4.0:1 and 4.7:1, pref 4.2:1-4.5:1. During 2nd stage the longitudinal orientation should be increased by 1.05:1-2.5:1, pref. 1.1:1-2.0:1. The two orientation treatments may be applied in continuous succession to each other to produce an extruded amorphous tubular film, or the 1st stage prod. may be reeled and stored prior to 2nd stage stretching. Used for packaging paste or pseudo paste matls. such as mastics, paints, etc. Biaxially oriented 1st stage film is stable to 2nd stage drawdown without generating significant lateral contraction, avoiding need for 2nd stage inflation to maintain the lateral orientation, obviating the need for a gas injection roll or needle and consequent problems in sealing the roll nips or making good a needle entry weld line along the skin.
