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 unwinding device comprises: a rotating element (3) with supports (13, 15) for at least two reels (B1; B2; B3); a splicing member (31, 33, 35) to join a first web material (N1) coming from an expiring reel (B1) to the initial free end (T) of a second web material (N2) wound on a new reel (B2). At least one mechanical member (21) is associated with each support (13; 15), to retain the initial free end (T) of the reel disposed on the support, to hold the initial free end until splicing of the two web materials.

摘要:
An unwinding system for handling reels of tissue, which for each laminar ply of tissue to be applied consists of two reel-carrier units onto which are mounted the respective reels, one of which supplies the laminar band for processing, whilst the other remains on stand-by to be spliced onto the processing line when the supply reel runs out, with the reel-carriers capable of vertical displacement, for the separate positioning of the respective reels, one in the upper part and the other in the lower part, for the preparation of the stand-by reel whilst the other is in the operating stage; with the reels mounted in the reel-carriers by means of attachment cones, by means of which unwinding rotation is controlled.
摘要:
A double-faced splicing tape of the present invention splices a first web used for forming a tobacco rod and a second web in a stand-by state to and has a plurality of perforations extending in a longitudinal direction of the webs. Furthermore, the present invention provides a feeding device for making the double-faced splicing tape hang toward a feeding position located in between a main delivery path of the first web and a sub-delivery path of the second web.
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.
摘要:
A process for splicing a first portion of absorbent material to a second portion of absorbent material to form a longer, continuous length of absorbent material suitable for uninterrupted sequential infeed to a processing machine. The process includes the steps of placing a trailing end of the first portion adjacent a leading end of the second portion and aligning the ends. A piece of splicing material is attached to the ends. The piece of splicing material has a fluid permeability at least about as great as a fluid permeability of the first portion of absorbent material and at least about as great as a fluid permeability of the second portion of absorbent material.
摘要:
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.
