Provided is a method for producing, with high productivity, a microporous plastic film having excellent physical properties and mechanical properties by preventing slip even in wet roller drawing. This method for producing a microporous plastic film is a method for producing a uniaxially or biaxially oriented microporous plastic film by kneading a diluent and a polyolefin polymer with an extruder, discharging the diluent-kneaded polymer from a die in a sheet form, cooling and solidifying the sheet discharged from the die on a drum, then reheating the solidified sheet, drawing the same in a sheet conveying direction with a plurality of rollers, cooling the sheet drawn in the sheet conveying direction, then gripping both ends of the sheet with clips, introducing the sheet into a tenter, and then cleaning the diluent, wherein: in drawing the sheet in the conveying direction, the sheet is drawn at the greatest ratio between the most downstream roller (B) in the conveying direction among said plurality of rollers, and a roller (A) that is driven by a motor and located next to said roller (B) on the upstream side in the conveying direction; and the ratio of the traveling speed of the clip, in said tenter, located on the most upstream side in the conveying direction to the peripheral speed of said roller (B) is set within the range of from -3% to +3%.

A fastener cartridge assembly (210) for use with a surgical instrument is disclosed. The fastener cartridge assembly can include a cartridge body (214), a plurality of fasteners removably stored within the cartridge body, and an implantable layer (220). The fastener cartridge assembly and/or the surgical instrument can include a lockout system (212) configured to deactivate the fastener cartridge assembly and/or surgical instrument in the event that the implantable layer is prematurely removed from the fastener cartridge.

The invention solves the problem of the manner of obtainment of mass for production of shaped construction elements. The manner consists of the fact, that in the mechanical mixer a ceramic granulate is placed, preferably in the form of pearlite and is soaked, preferably with water until complete soaking of the granulate and is mixed with the binding agent until obtainment of the situation, where each loose grain ( 1 ) of the granulate is coated with a layer of moist binding agent, creating a coating ( 2 ) around the grain. Priorly prepared moulds are filled with the obtained mass. The mass for production of shaped construction elements consists of 15-25 % of bond weight, preferably in the form of pearlite, 35-45 % of binding agent weight, preferably in the form of plaster with improved resistance parameters and 35-45% of water weight.
