According to the invention, there is disclosed a method of opening a package including a content wrapped with a wrapper. The method comprises the step of directing a laser beam to the wrapper for cutting the wrapper with the laser beam to open the package. The method further comprises the step of protecting the content from being damaged by the laser beam.

Package opening method and apparatus

A device for cleaning a cylinder of a printing machine of the type which uses a cleaning cloth stretched between a cloth supply roll and a cloth take-up roll and adapted to be brought into contact with the outer periphery of a cylinder in a printing machine by pressurizing means, the cleaning cloth being impregnated with a cleaning liquid before it is set in the device. Needing no cleasning liquid supply system or liquid supply control means, the device can be realized in a very simple and compact form, which allows for easy maintenance.

Device for cleaning a cylinder of a printing machine

A filter device suitable for use in cleaning dampening water used in an offset press. The filter device has a tank in which are defined three sections: a stirring tank section, a floating tank section and a discharging tank section. The floating tank section and the discharging tank section are communicated with each other through a passage at their lower regions. The passage is adapted to be selectively closed by a shut-off device which is operated periodically under the control of a timer. A floating contaminant removing opening es positioned above the water level in the floating tank section. The contaminated water is poured into the stirring tank section through a bubbling means so that contaminants are adsorbed by the bubbles. The bubbles adsorbing the contaminants are allowed to float in the upper region of water in the floating tank section. When the passage is shut off by the shut-off device, the water level in the floating tank section is raised so that the contaminants are removed together with the bubbles through the floating matter removing opening. On the other hand, the cleaned water free of contaminants flows into the discharging tank section through the passage and discharged outside the tank so as to be recirculated to the offset through a filter.
