This document analyzes internal trade costs in Canada using detailed trade and output data. It finds:
1) Internal trade accounts for around 11% of Canadian output on average and is as important as international trade for some provinces.
2) Estimated internal trade costs are large (8-15% of trade value) and vary significantly across sectors and provinces, with poorer regions generally facing higher costs.
3) Reducing internal trade costs by liberalizing sectors could significantly increase Canada's GDP and welfare, with gains estimated between $50-130 billion or 3-7% of GDP depending on the policy experiment. Highly interconnected industries have the largest gains from liberalization.

CLEANING EQUIPMENT SUCH AS A MOP, MADE
OF STRIPS OF ABSORBING MATERIAL
DESCRIPTION
A ?rst object of the invention is a process for the
formation of a cleaning implement, such as a mop imple
ment made up of strips of absorbing material or other
strips or bristles clenched or tightened between them.
According to the invention, a bunch of said strips (or
other) is clenched at one end and said end is introduced
into a mould for the injection of synthetic resin under
pressure; with the mould being closed, a clenching and
anchoring core of said strips (or other) is formed. Said
core ensures the connection with the handle for usage.
The core is advantageously moulded with a plurality
of injection directions from the periphery towards the
inside of the core and balanced; thereby ensuring the
centering and anchorage of the bunch of strips in the
core.
A further object of the invention is an apparatus for
carrying out the above process, which substantially
comprises: a device for temporarily clenching the ends
of a bunch of strips made of absorbing (or other) mate
rial; a mould that can be opened and is able to receive in
its cavity the clenched ends of said bunch of strips and
to close up so as to clench said bunch of strips by itself;
and in said mould, a plurality of injection orifices so
distributed so as to inject thermoplastic resin in a bal
anced manner, to ensure the centering of said clenched
ends and their anchorage.
The mould cavity may be shaped to create, on the
core, means for the engagement with a handle having a
body for the covering and engagement of said core.
Alternatively, the mould cavity may be shaped to di
rectly create the core with a ?nishing shape and a seat
for a stick or other handling member.
Another object of the invention is a cleaning'im
plement—such as a mop implement with a plurality of
strips made of absorbing material or bristles, formed by
the process and an apparatus as above de?ned, that is,
having a core of injection-moulded thermoplastic resin,
which clenches and anchors the ends of the strips or
bristles or other. Said core may be coupled to a ?tting
for the handle or, alternatively, said core may create a
?nishing shape with a coupling for a stick or other
handling member.
Through the above de?ned process and apparatus, an
implement can be realized having particularly simple
construction and with substantial economy, and above
all, it is possible to realize an improved mechanization
and thus an advanced automation of the operations for
the formation of said implement so as to realize a manu
facturing line which is in practice completely auto
mated.
The invention will be better understood by following
the description and the attached drawing, which shows
a practical, non-limitative exempli?cation of the same
invention. In the drawing:
FIG. 1 shows schematically an open mould with a
bunch of strips, bristles or other articles, clenched and
positioned therein;
FIG. 2 is a partial section view taken on line II--II of
FIG; 1; and
FIG. 3 shows a partially sectioned view of an imple
ment with a core, as it can be obtained by the apparatus
of FIG. 1.

According to what is roughly illustrated in the at
tached drawing, numeral 1 indicates an apparatus for
clenching a bunch F of strips with ribbons of ?exible
absorbing material of the type utilized as absorbent
cloths also in houseworks. The bunch F may be realized
with strips all of the same type or even with a portion of
strips of one type and another portion of strips of a
different type in order to obtain a dual functionality of
the implement. The clenching apparatus 1 comprises at
least two fork-like or otherwise shaped clenching mem
bers 3 to embrace the bunch of strips F which is intro
duced between said two wide open, that is, divaricated
members 3 in order to clench circularly in a more or less
homogeneous and uniform manner, according to an
arrangement like that shown in FIG. 1, wherein the
ends E of strips result clenched by said two members 3
of the apparatus 1; the operation of members 3 may be
carried out by ?uid-driven means 5, mostly ofhydraulic
or other equivalent type. The apparatus 1 may be sepa
rated from or advantageously associated with the
moulding apparatus.
The moulding apparatus comprises in practice two
substantially symmetrical parts of mould 7, which can
be closed so as to engage, through an edge 7A, the‘
bunch of strips F just next to the clenching zone B
obtained by members 3 of the apparatus 1; as to the rest
of mould 7, this can remain completely closed for the
injection, while in the zone of the edges 7A, the clench
ing ensures a suf?cient seal in cooperation with the
clenched strips. Numeral 9 indicates a means, shown in
an illustrative and summary way, for opening and clos
ing mould 7.
As can be seen in particular in FIG. 2, the two mould
parts have injection ori?ces, that is nozzles, 10 which
are distributed around the axis of the closed mould, in
such a way that the material, being injected under
strong pressure and plasticized, goes into the mould
with a substantially balanced distribution and thereby
acts on the clenched ends E of the bunch F in a substan
tially balanced manner, so that these ends E remain
substantially centered within the cavity of the mould
?lled with injected thermoplastic material. A core N is
thus formed-shown in detail through a view and a
section in FIG. 3—which embodies the ends E of strips
of bunch F and is also capable of penetrating under
pressure in particular between said strip ends, and even
inside the material of the strips in some particular condi
tions and with certain particular qualities ofthe material
of the strips and of thermoplastic material used. In any
case, the core N injected onto the ends E held inside the
mould ensures a stable anchorage of the ends of bunch
of absorbent and flexible strips or bristles.
The core N may be formed in the outside so as to be
coupled ?rmly to a covering and finishing body having
a seat for a stick handle or the like. Alternatively, the
core N may be formed so as to be removably screwed or
bayonet or otherwise jointed on a body even making
part of the recoverable handle, whereby the core N
with the bunch F represents a spare part for the unit
whose utilization of the covering and ?nishing body, as
well as of the stick is thus prolonged. Still alternatively,
the core N may itself be structured as a covering body,
aesthetically shaped and presenting a joint seat for the
stick.
In the illustrated example, the realization of a brush
like cleaning implement is provided, having a longitudi
nal axis of symmetry. Implements of different con?gu
ration may be realized by the described system, for
