A process for machine direction orientation of nylon films in which nip rolls are applied to both the slow and fast orientation rolls with a substantially uniform force in the range of 15 to 45 N/cm width of nip roll. The temperature of the slow roll is held between 70.degree. and 180.degree. C. and the temperature of the fast roll is held between the temperature of the first roll and 20.degree. C. below the melting temperature of the nylon film. The distance between the orientation rolls is in the range of 10 to 2050 .mu.m.

Machine direction orientation of nylon film

An apparatus is disclosed for dispensing a liquid packaged in a thermoplastic film pouch into a receptacle therefor. The apparatus comprises: (a) a funnel portion terminating at its outlet end in a spout, the spout being adapted to fit into an opening in the receptacle, (b) a pouch receiving portion integrally joined to the funnel portion at its inlet end and forming an extension of at least one side thereof, (c) a pouch support in the pouch receiving portion, the pouch support extending into the funnel portion and being adapted to support on its upper surface a pouch of liquid such that an ear thereof projects over the pouch support into the funnel portion, (d) cutting blades movably positioned beneath the end of the pouch support extending into the funnel, the cutting blades being adapted to be moved from their position beneath the end of the pouch support to a position further into the funnel portion so as to cut open the ear of the pouch, and (e) a coil spring connected to the cutting blades adapted to automatically return the cutting blades to their position beneath the end of the pouch support. The apparatus is useful for purposes such as: (1) dispensing motor oil into the crankcases of motor vehicles; (2) dispensing ethylene glycol antifreeze into the radiators of motor vehicles; and (3) dispensing windshield washer antifreeze and brake fluid into the respective containers therefor on motor vehicles.
