[Industrial applications]

 The present invention relates to a pressing device for pressing an oil filter (element) or the like.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional pressing apparatus has an advantage that a large amount of processing can be performed at one time, but has a drawback that a large noise is generated when an empty can is charged or when pressure is applied.

Further, particularly in the case of the drum type press device, unless the diameter of the drum is correspondingly increased, the empty can cannot be put into the gap, and thus the device becomes large in size. .

On the other hand, like an oil filter equipped in an oil circulation system of an automobile, if liquid such as oil remains inside the can body, the liquid will flow out at the time of pressing. The fact is that it has not been done, especially because the oil filter is incinerated for environmental reasons and then discarded, which is an uneconomical point that oil is not reused. .
