摘要:
In one form of the present invention, a system for constructing a laminate (122) is disclosed. The system comprises a ply feeder (101) that sequentially stacks one or more plies (100) to form a ply stack (102). A computer (106) directs a laser (104) to cut each ply (100) to a desired shape after becoming part of the ply stack (102). The ply stack (102) is then placed on a reconfigurable tool (112). An applied pressure compresses the ply stack (102) against the reconfigurable tool (112) while an actuator (124) subsequently reconfigures the reconfigurable tool pins (114) to a predetermined shape. In a more particular embodiment, a composites forming process is used, such as diaphragm forming, to compress the ply stack (102) before the reconfigurable tool pins (114) are reconfigured. In another particular embodiment, the reconfigurable tool pins (114) are first reconfigured then a vacuum diaphragm forming process is utilized to compress the ply stack (102) against the reconfigurable tool (112).

摘要:
A dispenser (10) from which sheet material (28) may be manually pulled from a supply of the sheet material carried on the dispenser through a passageway defined by a frame of the dispenser (10). The dispenser includes a cutting member (32) having a sharp cutting edge (34) adapted for transversely cutting the sheet material (28) and an elongate contact surface (36) generally parallel to and spaced from the cutting edge (34). The cutting member (32) is mounted on the frame for movement between (i) a retracted position to which it is biased at which the cutting edge (34) is positioned to restrict contact between a person using the dispenser (10) and the cutting edge (34) and at which the contact surface (36) extends along the one side of the passageway; and (ii) a cutting position to which the cutting member (32) can be moved from its retracted position by manually tensioning sheet material (28) being pulled from the dispenser (10) around the contact surface (36) of the cutting member (32). At the cutting position the cutting edge (34) is positioned to intersect and transversely sever the tensioned sheet material (28) being manually withdrawn from the dispenser (10).

A linerless label dispenser includes a cutting mechanism (27). Linerless label (22) are transported from a roll (10) underneath a plastic guide (18) and onto an adhesive-release material guide structure/ramp (19) past a sensor (24) to a print head (26) which prints indicia on the release material coated face of the labels. From the print head and cooperating print roller (28) the labels pass to a plasma coated stripper surface (31) which is disposed at an upwardly directed angle between about 20-35 DEG with respect to the horizontal, and into contact with a plasma coated stationary anvil blade (32). The anvil blade is spaced downwardly from the stripper surface a distance of about .001-.008 inches (preferably about .002-.004 inches) and cooperates with a plasma coated or texture painted rotary blade of a rotary cutter (38). Downstream of the blades may be a plasma coated exit roller (43) typically cooperating with a hold down mechanism for dispensing individual cut labels.

To implement a process for operating a device for making labels from strip material with a roll (1) of strip material, a feed device (2, 3) for the strip material, clamping tongs (16) to take the end of the strip from the feed device, a folding sheet (23) which inserts the strip between the jaws of positioning tongs (8) which transfer it to a processing device, and a separating device (7) to separate the strip from the strip material, by means of which strips of different lengths can be simply folded and processed, it is proposed that the movement cycles of the components of the device are controlled in such a way that, after the end of the strip has been transferred to the clamping device, first of all the folding device advances towards the positioning device, then the separating device (7) separates the strip from the strip material upstream of the feed device (2, 3) and either the positioning device closes and secures the folded strip while the folding device returns to the initial position, or after the strip has been separated the folding device advances until the strip is unfolded, when the positioning device closes and the folding device returns to the initial position.
摘要:
A system for laying up multi-layer stacks of sheets is particularly well suited for making pads of notes having ultra-removable adhesive coatings applied in a narrow strip to the back of each sheet. Large sheets having areas many multiples larger than the size of the individual pads, are applied from a continuous paper web having zone coated adhesive strips applied thereto onto a series of recirculating pallets each of which serially receives a large sheet. The web is applied by pressing the adhesive coated side onto the pallet as the pallet travels through a nip formed by the web carrying roll. Closely spaced end-to-end register of the pallets is maintained through the web-applying nip roll and a perforating blade cooperates therewith to form a weakened tear line across the width of the web which is synchronized to coincide with the gap between adjacent pallets. A severing station downstream of the web applying roll causes rapid displacement of the pallet from the one immediately upstream and severs the web along the tear line, resulting in a large single sheet adhering to each pallet. As the pallets recirculate through the system, multiple layers of sheets are laid upon one another until a desired number of sheets has been attained. The large stacks are subsequently cut along multiple parallel lateral lines, and along longitudinal lines corresponding to the positions of the adhesive zone coats and desired final pad widths, respectively.
摘要:
The invention relates to an apparatus for the manufacture of insulating chutes. The apparatus comprises means for winding plies of insulating material on to cores; means for curing the insulating material wound on the cores; means for removing cured insulating material from the cores; and means for returning empty cores to the winding step. The object is to make the operation of this kind of apparatus more efficient than previously. The object is achieved in such a manner that the cores (12) are arranged in groups on an endless transporter (1), whereby empty spaces corresponding to the number of cores in a group are left between the groups of cores, and the transporter is arranged to move step by step a distance corresponding to the interspace between individual cores in a group when the first core in each group reaches the winding means, and a distance corresponding to the interspace between the groups when the last core in each group leaves the winding step. When the transporter is displaced a distance corresponding to the interspace between the groups, the whole group of cores is introduced into the curing means (5), in which the group of cores is detached from the transporter for the time of the curing, being thereafter returned to the following empty space on the transporter.
摘要:
Device for the manufacture of and removal by groups of synthetic material bags produced from a flat band shaped as a tubular sheet, which is displaced intermittently. A holding device is arranged behind a cutting device in the feed direction of the band. It holds each bag separate from the band in the area of its open edge. To provide such a device having a simple construction, and allowing the manufacturing of non perforated bags, the holding device is comprised of a suction box (32) provided with two rows of suction holes (33, 34) arranged in the region of the conveying plane, perpendicularly to the conveying direction. The distance between those rows corresponds approximately to that of the groups of bags arranged one on top of the other. A pressure cylinder (35), moving vertically, is capable of going down each time on the bag arranged in the last position. It cooperates with a counter pressure cylinder (37) arranged underneeth the upper side of the conveying belt (5). It is controlled so as to be lowered substantially only during the intermittent feed of the conveying belt (5).
