Abstract

A machine configured to produce stacks of folded pop-up wipes includes a holder, a first tension unit, a folding unit, and a control unit. The folding unit includes two or more folding rollers each including a hub including grippers to grip and release the material and infeed plates to feed the tissue to respective grippers of the other roller. Positions of the infeed plates are adjustable in relation to positions of the grippers Distances between the grippers and the infeed plates adapt a width of the produced stacks of wipes. The control unit is communicatively coupled to the first tension unit and the folding unit and includes a processor, and a memory. The memory contains instructions executable by the processor. The material is threaded along a path through the machine via the first tension unit and the folding unit. Executing the instructions causes the control unit to control the machine.

Abstract

A machine to produce stacks of folded pop-up wipes from material that is threaded along a path having a direction through the machine. The machine includes a holder, a first tension unit, a perforation unit to generate perforations in the material in a direction orthogonal to the direction of the path, and a folding unit to fold the material in a direction orthogonal to the direction of the path. The material is threaded along a path through the machine via the first tension unit, the perforation unit and the folding unit. A control unit controls the machine to produce folded pop-up wipes by individually controlling tension of material along one or more sections of the path and to increase tension of the material in a section of the path located after the perforation unit to stretch a generated perforation in the section of the path by a target distance.

Abstract

Embodiments of this disclosure provide for a data compression method and a related data compression apparatus. In the method, to-be-compressed data and a length limit value for data compression are obtained. When the length of the data obtained by compressing the to-be-compressed data is greater than the length limit value, the to-be-compressed data is segmented based on the length limit value during compression. After the to-be-compressed data is segmented, the to-be-compressed data includes at least two compressed files after compression and a length of each compressed file is less than the length limit value.
