Abstract: Packaging packages in plastic film is an important part of industrial and commercial processes. Packaging leakage is expensive, but improved package welding is difficult and time-consuming and so also expensive. This is solved by providing a packaging apparatus (100) with plastic film welding means, further having: an optical sensor (110) to provide images (164) of a film weld (11, 12) produced by the packaging apparatus (100) and transmit said images as an image signal, a database (160) having contouring instructions (161 ) and a tensile algorithm (165), a processor (121 ) for receiving said image signal and adapted to: - generate weld data (170) from the image of said image signal by using said contouring instructions (161 ), where contour lines (171 ) of said weld data are generated for locations in the image with a high contrast, and where at least some of said contrasts correspond to boundaries between areas of welded film and unwelded film, - predict tensile strength of a weld (11, 12) based on said contour data (170) using said tensile algorithm (165), and - transmit a fault signal if the predicted tensile strength of a weld is below a certain tensile strength threshold.

Abstract: A valve (30) to be used when blowing air into squeezing pads (12) from a high pressure blower (32), such as a side duct blower, said valve (30) comprising a valve chamber (40) comprising a primary set of openings with a first opening (42) connected to said high pressure blower and a second opening (44) connected to said squeezing pads, whereby air can be transferred through said valve chamber between said squeezing pads and said high pressure blower, said valve chamber further comprising a third opening (46), whereby air from said first opening can pass through said third opening, and where air not passing through said third opening passes through said second opening, said valve further comprising a valve spool for blocking (48) said third opening and thereby changing the amount of air passing through said third opening. The valve spool for blocking said third opening comprises a limiter element (49, 1101), wherein said limiter element and/or said third opening (46, 1103) has a varying diameter along its longitudinal axis (47), where the limiter element is adapted to be inserted along its longitudinal axis in said third opening, and where the extent of insertion of said limiter element changes the amount of air passing through said third opening. The invention further relates to a lift head with the above valve.
