Film supply apparatus (2) has two film holders (22a, 22b) supporting two rolls of film as film (101) on a use side and film (100) on a stand-by side respectively, feed rollers (3) for feeding film (101) on the use side, film holding member (34) holding a leading end portion of film (100) on the stand-by side, sucker (36) pulling back film (100) on the stand-by side upstream in a feeding direction and heater bar (31) heat-sealing two films (100, 101). Sucker (36) attracts film (100) by suctioning and pulls film (100) back to a position where a leading end portion thereof faces heater bar (31).

The splicing device comprises two heads (41A, 43A; 41B, 43B), each of which has: a roller (33A; 33B) associated with a clamping bar (93A; 93B) to hold between said roller and said clamping bar an initial edge (L) of the second web material; a counter-pressure member (53A; 53B) cooperating with said roller to press said first and second web materials against each other; and a cutting member (67A; 67B).
摘要:
A tape splicing mechanism joins the tail of one tape to the leading edge of another tape. A frame defines a passageway along which the tape passes. A pair of arms rotatably attached to the frame have projecting posts and rotate between a first position where the posts are closer to the pathway and a second position where they are further from the pathway. The arms are urged toward the first position and a catch mechanism holds them in the second position until released by a release mechanism when a release indicia in the first tape passes. The leading edge of the second tape is looped around the first tape to form a loose knot and is tied to the post on each side of the first tape. When the arms are released they move to the second position and tighten the knot.

There is provided an apparatus for joining films wherein a rear end portion of a preceding film and a front end portion of a trailing film are mutually joined without using a joining material such as an adhesion tape or the like to sufficiently contribute the joint portion to heat seal likewise the other portions of the films and realize excellent liquid tightness and airtightness of the joint portion itself and also tensile strength required for the film itself is given to the joint portion. The apparatus comprises a fuse seal means arranged in the vicinity of a running path of the preceding film, a film-holding means holding the front end portion of the trailing film at a side opposite to the seal means with respect to the running path, an insert plate pushing the front end portion of the film held by the film-holding means into the seal means together with the preceding film, and an extra film removing means clamping a turnup portion of the preceding film pushed over the seal means by the insert plate and separating from a fuse-sealed portion.

Automatic splicing device for laminar webs in continuous feed processes, consisting of two reel-carriers (1 and 2), mounted above which are the respective preparation heads (3 and 4) and between them a moving head (14) capable of displacement between the positions of said preparation heads (3 and 4), for the preparation in either of these of the web from a reel in stand-by for the subsequent joining to the web of another infeed reel when the latter runs out, without any interruption to the feed process.
摘要:
A supply of sheet stock material for use in a cushioning conversion machine is disclosed. The supply of stock material includes at least one ply of sheet stock material rolled or folded into a compact configuration such as a roll of wound stock material or a stack of fan-folded stock material. The ply has disposed on a leading or trailing end thereof, a pressure sensitive adhesive layer and a removable release liner covering the pressure sensitive adhesive layer. When a supply of sheet stock material is almost spent, a succeeding supply of stock material may be spliced to the almost spent supply by removing the release liner to expose the adhesive and then applying the leading or trailing end, having the adhesive thereon, to a trailing end of the almost spent supply of stock material or leading end of the succeeding supply of stock material.

A method for processing high bulk tissue webs is disclosed for forming a wet web, drying the web, winding the dried web to form a plurality of parent rolls, unwinding the parent rolls by transmitting torque through the roll center and/or ends, moving the partially unwound roll to effect splicing with a subsequent parent roll, and rewinding the thus united web. In particular embodiments, the torque transmitting means comprise side clamping mechanisms that engage only the end surfaces of the parent rolls. In other embodiments, an automated off-line method for splicing tissue webs from different parent rolls utilizes a finishing unit that substantially continuously impacts each web during unwinding to splice the webs together. In one aspect, a method of making and processing high bulk tissue webs is disclosed for the production of a soft, high bulk uncreped throughdried tissue web by depositing an aqueous suspension of paper-making fibers onto an endless forming fabric to form a web and drying the web by throughdrying to final dryness without any significant differential compression to form a dried web having a bulk value of about 15 to 25 cubic centimeters per gram or greater, an MD Stiffness Factor of 50 to 100 kilograms, a machine direction stretch of 15 to 25 percent, and a substantially uniform density.
摘要:
A tail for adhering the tailing edge of a first roll of tape that is being fed to an application device to the leading edge of a second roll of tape without stopping the tapes includes a bulge which is located in the tail and has an adhesive coating on each side. A first protective element located on the tail releasably covers the adhesive coating on one side of the bulge and a second protective element located on the other side of the bulge releasably covers the adhesive coating on the other side of the bulge when the tail is wrapped onto a roll base. The leading edge of the second roll of tape is wrapped around the tape from the first roll to form a loose knot and then is threaded through a pair of pincher rollers through which the first roll of tape is fed. Thus, when the bulge passes through the pincher rollers it becomes adhesively attached to the leading edge of the second roll and the knot is tightened around the second roll and a mechanical joint is formed between the tapes.
