摘要： A circular weaving machine (1, 1′) has warp-tape guide elements (2) which are arranged around a circular reed (4, 4′) in order to supply a multiplicity of warp tapes (3). Weaving-shed forming devices (5) group the fed warp tapes into two warp-tape groups (10, 11) and impart thereon mutually opposed alternating movements, with the result that a weaving shed (9) is opened and closed between the two warp-tape groups. A weaving shuttle (12) moves on an orbit in the opened weaving shed (9) and, in the process, introduces a weft tape from a weft-tape bobbin (13) carried thereby into the weaving shed (9), with the result that a fabric is formed. The fabric is drawn off through a weaving ring (15). The weaving shuttle (12) keeps the bobbin axis (13a) of the weft-tape bobbin (13) at an angular position which deviates by at most +/−15°, preferably at most +/−10°, from a normal to a surface (9a, 9a′) which contains the geometric connecting lines between the warp-tape guide elements (2) and the weaving ring (15).

摘要： A device and a method for applying cover sheets to cross-bottoms of tubular sections made of a plastic material. The device includes conveyor devices for transporting the tubular sections and for depositing the cover sheets on the cross-bottoms in a deposit area. The device includes a hot gas device with a gas heater and a nozzle connected to the gas heater and oriented toward the deposit area for the cover sheets so when gas is supplied to the gas heater, the gas flows along a flow path from the gas supply through the gas heater and the nozzle into the deposit area. The hot gas device has a hot gas reservoir with an internal volume for the temporary storage of hot gas, the flow path running through the hot gas reservoir. A gas mass flow ({dot over (m)}1, {dot over (m)}2, {dot over (m)}ges) of gas supplied to the gas heater is adjustable by a control.

摘要： A device and a method for extruding plastics, comprising an extruder screw, a housing with a cavity, a drive unit for rotatably driving the extruder screw, a heating element arranged on the housing alongside the extruder screw, a filling unit through which shredded plastic can be supplied into the cavity, and a filler metering device. Upon rotation, the extruder screw conveys the shredded plastic in the transport direction along a longitudinal axis of the extruder screw. The housing has a feeding port for the filler opening into the cavity, wherein the filler metering device is connected to the feeding port and is designed for supplying a filler dispersed in a gas stream into the cavity.

摘要： Cutting device for longitudinally cutting a film web, in particular a plastic film web, moved in a web plane in a transport direction into a plurality of film bands, wherein a first cutter bar provided with cutting blades is immersed with the cutting blades in a cutting position into the web plane. In order to replace the cutter bar, a second cutter bar provided with cutting blades may be immersed with its cutting blades into the web plane, wherein the first cutter bar may be moved from the cutting position into a transfer position outside of the web plane when the second cutter bar is immersed with its cutting blades into the web plane.

摘要： The invention relates to a winding machine (1) with a winding machine fixing mechanism (44) for fixing a winding sleeve (4) on a winding spindle (3). The winding machine fixing mechanism (44) can be actuated by use of a motion control. By this motion-controlled actuation, the winding machine fixing mechanism (44) can be transferred from the release position into a fixing position and/or from a fixing position into a release position. During the motion control, a catch (5) is entrained by the movement of the winding sleeve (4). This catch then causes the actuation of the winding machine fixing mechanism (44).

摘要： A web material made of a woven fabric is divided into web sections by tear lines. The tear lines weaken the web material without causing a complete separation of the web sections from the web material. The web sections are separable from the web material by being torn off along the tear lines. Cuts are formed in the woven fabric along transverse sections of each tear line, the transverse sections running essentially transversely to the longitudinal extension of the web material, which cuts are spaced apart from each other and are oriented in the longitudinal direction of the web material or transversely to the transverse section of the tear line, with the cuts being connected to only one transverse section of the tear line.

摘要： A bag for loose material, wherein the bag is formed from a tubular material, which tubular material is a tubular planar assembly or a flat material connected to form a tube, and has a first and a second open end. Sections of the tubular material of one of the ends are shaped by folding to form a bag bottom. The bag bottom exhibits a first cover sheet and a second cover sheet. The first cover sheet is connected to the bag bottom and extends in a first region of the bag bottom. The second cover sheet is connected to the bag bottom and extends in a second region of the bag bottom. Via the cover sheets, the folded sections of the tubular material are held together in such a way that the bag bottom is sealed.

摘要： The device for cooling an adhesive applied to a surface of bag bodies includes a transfer conveyor and a cooling conveyor. The transfer conveyor conveys the bag bodies at a transfer speed to the cooling conveyor, and the cooling conveyor conveys the bag bodies taken over from the transfer conveyor at a cooling conveyor speed. The transfer speed is higher than the cooling conveyor speed, which is why the bag bodies are arranged overlapping each other on the cooling conveyor. Due to this higher packing density, there is achieved a long dwell time of the bag bodies in the cooling conveyor at simultaneously a high flow-rate of bag bodies through the device.
