Abstract: The invention relates to a method and a device for depositing a flexible material web, said web being introduced into a folding unit and being deposited from said folding unit at a depositing point. The aim of the invention is to achieve higher production speeds with an excellent fold quality, even for material webs with a low weight. To achieve this, compressed air is applied to the material web after the latter has exited the folding unit in order to support the festooning process by means of a blower device.

Abstract: A machine for converting a fabric from a rolled fabric into a superimposingly folded fabric for delivery to a dyeing machine. The machine includes a frame, a cradle, and a carriage. The frame rests on an unyielding surface. The cradle is operatively connected to the frame, holds the rolled fabric, and dispenses the fabric from the rolled fabric. The carriage is movably mounted to the frame, and receives the fabric dispensed from the rolled fabric, and in response thereto, moves back and forth relative to the frame to dispense the fabric into the superimposingly folded fabric for delivery to the dyeing machine.

Abstract: A folding device for folding continuous paper, which is previously provided with fold lines at given intervals, along the fold lines in a zigzag pattern. The folding device comprises a feeding member of the continuous paper, a swinger fin that swings using its one end as a fulcrum like a pendulum in synchronization with the fold lines while feeding the continuous paper into its inside, and a table to be surmounted by the continuous paper that has been folded. The swinger fin includes a feed roller pair for feeding the continuous paper while sandwiching the paper therebetween, and at least a pair of guide plates facing each other with a given gap therebetween, in which the continuous paper is fed through the gap. One of the feed rollers constructing the feed roller pair and one of the guide plates, which are located on one side of the continuous paper, can be integrally opened or detached from the swinger fin.

Abstract: Roof insulation applicator (10) for applying sheet material to the roof of an industrial building includes a carriage (12) for mounting on adjacent purlins (14 and 15) of a partially completed roof. Support roller (40) is applied by the carriage to the upper surfaces of the purlins (14 and 15) and the carriage is tiltable about the support roller (40). The center of gravity of the carriage (12) is applied rearwardly of the support roller (40). Purlin engager (60) is mounted to the front of the carriage and engages under the upper laterally extending flange (22) of the purlin (14) and limits the downward pivoting of the rear end of the carriage applying a lever arm effect by the weight of the rear portion of the structure to the support roller (40). This firmly holds the sheet material in its stretched configuration extending from the roof panel (16) out to the support roller (40), reducing the tendency of the sheet material to sag in between the adjacent purlins.

Abstract: An apparatus for propelling a carriage along a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement, and method of using same are disclosed. The apparatus includes a carriage movable along the length of the purlins for dispensing a support sheet from a roll for support of insulation material as the carriage travels along the length of the purlins so that the support sheet depends from the top portion of adjacent purlins. The apparatus further includes a puller assembly attached to the carriage. The puller assembly includes a driven wheel frictionally engaged with a surface a purlin, and a drive mechanism for rotating the driven wheel.
