A method of stacking a plurality of absorbent sheet products is provided. In an embodiment, the method includes folding an absorbent sheet inwardly along a first folding line to form a first inner panel, folding the absorbent sheet inwardly along a second folding line, substantially parallel to the first folding line, to form a second inner panel, folding the absorbent sheet along a third folding line substantially perpendicular to the first and the second folding lines to form a first outer panel and a second outer panel, sandwiching the first and the second inner panels therebetween to obtain one of the absorbent sheet products, and inserting at least a section of at least one of the first and the second outer panels of each one of the absorbent sheet products between the first and the second outer panels of an adjacent one of absorbent sheet products of the stack.

Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.

A stack of interfolded absorbent sheet products comprising a plurality of absorbent sheets and a method of folding and stacking the same. Each one of the absorbent sheets is folded twice about a first axis to define two inwardly folded inner panels and at least once about a second axis to define at least two outer panels sandwiching the inner panels therebetween. The second axis is substantially perpendicular to the first axis, Each of the absorbent sheet products comprises at least one outer panel at least partially sandwiched between a pair of outer panels of an adjacent one of the absorbent sheet products of the stack. Each one of the absorbent sheet products is entirely detached from all other absorbent sheet products of the stack.
